This great old classic still is essential for dental health - buy it - use it!
In this throwaway society where appliances, especially electronics, are considered obsolete sometimes before the batteries need recharging, it’s amazing to find one product that is still virtually unchanged after over 50 years on the market. It hasn’t needed any upgrades, and is still basically the exact same function and design as it was way back when. I particularly find this gratifying when I just learned, for example, that Apple will be issuing an upgrade on their OS system for their IPhone, which will basically make any of their phones from the 4S and below obsolete, so that, even though yours may work perfectly, technically, you would have to throw it away and spend many hundreds of dollars for a new one! This appliance that has stood the test of time is the WaterPik. I remember my father buying one of the first ones, per his dentist’s recommendation back in the 1960s. In those days there was something about it that seemed almost futuristic. Like something you would see someone using in outer space in a SCI Fi flick. However it’s simple design and function was enormously easy to master, which is a big deal for me back then as little kid! It is also quite uncommon, when it came to devices that supposedly promised some kind of improved health, to find that everything they say about the produce… is true. I remember year after using it, and going from my annual checkup at the dentist, the results were amazing. I stopped using the WaterPik years ago, and just depended on regular brushing and flossing. However now that I’m not such a young kid, even with diligent dental hygiene, you’re gums will begin to do some receding on their own, purely by the evil tyrant known as “aging”. My scores for my gums receding were getting a bit worrisome, in the last few dental checkups, and again my dentist recommended that I should also use a WaterPik. To be honest I was surprised they still made them. I felt, like most everything in the world, these had fallen out of style or favor and we’re no longer used. My dentist however told me they were perhaps one of the best dental hygiene Home Devices ever invented and he was sorry to see that most people didn’t use them anymore. I told him that I flossed religiously, but he told me that the WaterPik gives an extra much needed work-out to the gums keeping them healthy and strong and reducing gum receding. So of course I went right onto Amazon, and found this unit. It was basically the same as I remembered, though they have streamlined the device a bit. Again it was easy to use, and starting with a low pressure number, I quickly got used to the pulsating action and within a week was at the highest level (yes, as “Spinal Tap” guitarist Nigel Tufnel would say: “it goes to eleven!”). The unit is actually a bit quieter than the original with an easier water reservoir system and a coiled hose which makes placement back on its “holster” a lot easier. It also has several holders for each individual pick if more than one of you is using it. Since I’m the only one who uses it, I simply keep the pick itself on the hose unit which fits easily on the hose-holster. Putting it back in its little holder which is situated behind the water reservoir is a little awkward, and frankly if you’re the only one using it there’s no reason to just keep it attached. So on to the punch line. After only six months of use, I went back for my dental checkup, and went through the rating test for gum receding, and found that all my numbers went up 50 to 70%! My dental hygienist, who does the tests, was so excited that she literally ran into the hall to show others, like a proud mother showing off her son’s report card. I feel like a little boy again, and was just a little upset that they no longer give out lollipops as rewards! One thing my dentist and dental hygienist did tell me is that if you use the WaterPik, you should continue to floss, since there are things that the actual floss does between your teeth which a WaterPik cannot. And of course things that the WaterPik can do that flossing doesn’t. So the combination of the two is extremely important. I’m at the age where friends are beginning to tell me about real trouble with their teeth, and how many are getting bridges and implants, and in one case even dentures, since their gums have receded so badly that their original teeth had to be removed (and we’re talking about folks in their late 40’s to early 60’s here, not ancient people). So I cannot stress hard enough how important something like a WaterPik is. And also, how important it is to start this kind of dental hygiene when you are young. For me, especially as you get older, there is nothing more constantly prevalent than when you have bad teeth. I don’t think anything else destroys your quality of life more than trouble with your teeth and the consequences it causes. By the way, after doing a lot of research I have found that Amazon gives the absolute best price for the WaterPik. Of course it arrived within days and like all other products has a great return policy.

Really is a great way to floss dentist recommendation
Works great, after brushing I was surprised to see the stuff stuck between teeth it removed that the brush missed, I add a little mouthwash to the tank , the adjustment for the pressure is helpful as full power can be painful turn it down a little and it still works great and did not hurt, last thing I really like is the off switch on the wand , turn off then I am not fumbling trying to find the power button a quick rinse and it’s ready for next time

Works great, easy to use. Takes getting use to not getting water sprayed on you. Wished was smaller
Been using this couple months, easy to use. Love the different strengths you can have water intensity. It can be messy (but it is just water) until you figure out best way to start and stop. Has power button to start , then on handle you can push on and off. It seems to work well as I find you almost have debris from your mouth loosen and can see in sink. So you know it works well even after brushing. Wished it was slimmer in design as takes up lots of space if leave on counter. So measure where you plan to store it to be sure it fits unless you place in drawer/cabinet. I tend to not use as often if not on counter. Could be a little quieter too, but not enough that I regret buying, maybe they will upgrade to quieter and slimmer model in future.

Waterpik Aquarius Blue WP-663 Blue Water Flosser For Teeth Cleaning
Effective Water Flosser That Makes Dental Care Easier. The Waterpik Aquarius WP-663 Water Flosser has been a very worthwhile addition to my oral care routine. After using it consistently for several weeks, I can definitely tell a difference in how clean my teeth and gums feel compared to brushing alone. It does an excellent job flushing out food particles and plaque from between teeth and along the gumline, especially in areas that can be difficult to reach with traditional floss. One of the standout features is the wide range of pressure settings. Whether you prefer a gentle cleaning or a more powerful stream, there’s a setting that can be adjusted to your comfort level. I started on a lower setting and gradually increased the pressure as I became more comfortable with the device. The water pressure remains consistent throughout use and provides a thorough cleaning experience every time. The large water reservoir is another feature I appreciate. It holds enough water for a complete cleaning session, so I rarely have to stop and refill it. The included assortment of tips is also a nice bonus, allowing different members of the household to use the unit or making it easier to target specific dental needs. The controls are conveniently located, and the pause button on the handle is especially useful when moving between different areas of the mouth. I also noticed that my gums felt healthier after incorporating this water flosser into my daily routine. My mouth feels fresher after each use, and routine dental cleanings have been easier since I’ve been using it regularly. For anyone with braces, dental work, or simply trouble using traditional floss, this product can make maintaining good oral hygiene much more convenient. The reason I’m giving it 4 stars instead of 5 is because it does have a few minor drawbacks. The unit takes up a decent amount of counter space, which may be an issue in smaller bathrooms. It can also be somewhat noisy while operating, and there is a learning curve when first using it. Expect a few splashes and a little mess during the first several uses until you get the technique down. Additionally, the water reservoir could be easier to clean thoroughly. Despite those minor complaints, the overall performance more than makes up for them. The Waterpik Aquarius WP-663 is reliable, easy to operate, and delivers a noticeably cleaner feeling than brushing alone. It has become a regular part of my daily routine, and I would recommend it to anyone looking to improve their oral hygiene. It’s not perfect, but it’s a high-quality product that delivers excellent results and is well worth considering.

Great product
I have had many of these over the years but this particular model is so far the best in many ways. It has a very easy soft touch on/off button making it super easy to use and a convenient storage space for the pics. I would recommend this to anyone looking for a waterpik it is the best way to floss, in my opinion, to keep up with dental hygiene.

Many settings, Amazing
This water flosser works great, cost is budget friendly. It was packaged very well no damage and was delivered quickly. I’ve used it twice and it feels like I just got a really good cleaning from my dentist . I bought dark blue looks nice, controls are easy to see while using. I would highly recommend this product.

Value for money
Great product but it’s a bit loud compared to the others I have used before. The water reservoir is really handy and I don’t have to refill mid clean. I don’t have to worry about the battery life since it is also plug in which just makes sense to me. Battery life is not something to worry about since the power is always on. No need to charge.

Make no Mistake - This is a Better Waterpik
Looking at the reviews, there seems to be a consistent effort by what I take are some owners of the venerable Waterpik WP-100 Ultra to trash this new model and portrait it as inferior to the WP-100. I don't think this is the case, the WP-660 is an improvement over the WP-100 in many ways and I'll tell you why later. The funny thing is that when I bought my WP-100 about six years ago, there were some reviews from what I take were owners of the revered WP-60 Classic trashing the WP-100. I take some people prefer the old to the new and that's OK. But I think some reviewers are being unfair to the Aquarius I owned a WP-100 that lasted for little over six years, used almost every day by two people, those are a lot of days so the WP-100 is an outstanding product. I did have to replace the water reservoir once due to the cheap rubber valve mechanism -improved on the Aquarius as you will see- that failed after three years of use and started leaking. Also, the hook for the handle broke -also improved on the Aquarius- and it was very difficult if not impossible to hang the handle onto the Waterpik body, I had to makeshift a Velcro handle that looked terrible. Googleing around I was surprised to find that this is a common issue with the WP-100, some owners have replaced the entire unit just because of a broken handle as there is no spare part available from Waterpik. Boomer But other than those two issues, my Ultra worked flawlessly, I never had to replace the hose or the handle as some owners had to, the on-off switch never failed and it worked the same way it was when new until an accident damaged the power-cord and it stopped working. Given its state with the handle hook and its age, I thought about self-repairing it but then I decided it was time for a new unit. At first and reading all those pro-WP-100 anti-WP-660 reviews I was tempted to get another WP-100, but the price of the Aquarius was about the same as the Ultra so I decided to give it a try I'm glad I did. The first thing you notice with the Aquarius is its modern look and high quality materials, all white and clear, and gorgeous, a significant design improvement over the WP-100. It is also lighter, which some can argue is a good thing -like me- and some can argue it is a bad thing because it "feels" cheap, which is also a valid point. The important thing is that its weight doesn't compromise its operation in any way, it won't tip-off when used nor will slide or be unstable, it is just lighter. It might be due to the use of cheaper materials on the pump as some have argued here, or just lighter materials, an overall technological improvement rather than cheapening the unit off. I guess time will tell which one is more durable, or we will have to open both units and compare its guts to get a final answer. So, why is the Aquarius better than the WP-100, other than it looks? -The WP-660 is less noisy and runs smother than the WP-100, you notice this right away. This with no compromise to the water pressure, the pressure is steady, as or more powerful than the WP-100 but it runs better, it sounds less stressed. Same or better results with less noise. -The hook for the handle was replaced by a sturdier piece and a different design to hold the handle, which reduces the pressure on the piece. With the WP-100, it was very easy to push the handle all the way down the hook, either by accident or just because of its design, stressing the hook and eventually breaking it; there was nothing to stop the handle to slide all the way down. As said, mine broke. That was a poor design, fixed on the Aquarius; now you just put the handle on the holder, it cannot be pushed all the way down. Some have argued that makes it difficult to handle the hose, but I didn't find any issues, the hose juts hang there by simple gravity, it doesn't tangle or interfere with the unit in any way -The reservoir valve was replaced by a metal spring mechanism. This was a another design flaw of the WP-100, its reservoir valve consist of a rubber piece, very cheap in my opinion, which eventually gives up and start leaking after a few years. As said before, the only way to fix it is by buying an entire new reservoir as the little rubber piece is not available alone, which means not only paying way more but also a waste of resources. In contrast, the WP-660 has a stainless steel spring with a plastic cap, that appears way more durable and also a much better and higher quality solution. Only time will tell but it seems it will last longer than the one in the WP-100 -The knob to graduate the pressure is easier to operate. The WP-100 has a hole to put both fingers in, on the Aquarius is a protruding knob, very easy to reach and to manipulate, way better I think, easier to find when in use if needed. And also more ergonomic -The Aquarius handle has an on-off switch that actually works. The WP-100 has that dreadful push button on the handle that you need to press constantly to stop the flow of water, doesn't stop it completely and also causes the Waterpik to make a noise like the pump is being damaged while the pressure is reverted. Not good at all, it was a poor solution at best, a useless feature at worst, it just didn't work. On the WP-660, there is an actual on-off button; in fact the correct way to operate this new Waterpik is to turn it on the base first, then turn it on via the handle when you already have the tip inside your mouth ready to go, the water doesn't come out unless you turn the handle on. This is much better than having to reach the switch on the base unit with the tip in your mouth or having to hold into the appalling pressure cutting button on the handle and then release it. All this while water was still coming out of the tip as the button didn't cut the water flow completely. -The pace timer. This feature is non-existent on the Ultra, and I realized it is very helpful. I use the Waterpik first on the upper section of the mouth, outside-inside and then move to the lower section, in-out and I'm done. At a pressure level of 8, the water in the reservoir, at full capacity, should last little less than 90 seconds. The Aquarius will give you a very short flow pause at 30 seconds of use and another at 60 seconds, this is good to pace your cleaning as it should take about 30 seconds to clean each part of the mouth, up and down, and then you have an extra 20 seconds to touch-up. This avoids you having to be periodically peaking over to the reservoir to see how much water is left and instead allow you to concentrate on the cleaning and doing the job properly -The reservoir cover is now part of the unit. If you are like my mother in law that misplaces everything - sorry mom, I still love you-, chances are you have misplaced the reservoir cover of the WP-100 (as my mother in law did). This cover also contains the tips so it can be kind of an inconvenience to lose it. On the WP-660, the cover is attached with a hinge mechanism to the body of the Waterpik, no way to lose it. The tips are now stored on the unit itself, behind the reservoir The rest is about the same as the WP-100, it comes with a bunch of tips from which you will probably only use the classic jet, and a 3 years warranty. It also includes a gum massaging mode which is pointless as you can achieve the same results by regulating the pressure knob. One disadvantage to the WP-100 is that you can only store two tips on the unit and not four, but again if you are like me that use only one, this is not an issue. But it might be for some users, if you have braces for example or like to regularly use the one designed for root canal maintenance (the Pik Pocket). One thing that was bad on the WP-100 and remain as bad on the WP-660 is cable management, there is no place to wrap the cable or at least a Velcro band included to deal with the cable, this lack of cable management is in part responsible for the damage to my WP-100 power cord, the cord is just hanging there. A needed improvement for the next design, please take note Waterpik Overall, I see no disadvantages when compared with the WP-100 and instead see many advantages. Until the unit has more years in the market, speculating about its durability without real facts is pointless at this time, so far the Aquarius works the same or better than the Ultra so it's higher price is justifiable. And you can even get a good deal and get it at the same price or a little cheaper than the Ultra, which is a real bargain

Outstanding customer service from eGency Limited
★★★★★ Outstanding customer service from eGency Limited I would like to commend eGency Limited for their truly excellent customer service. My Waterpik arrived extremely quickly, exactly as promised, and it was beautifully packaged and presented in a very professional manner. Unfortunately, I later discovered that the model supplied was a US 120V version, which was not suitable for my UK electrical supply. I contacted the company, and I was genuinely impressed by the speed, professionalism and courtesy of their response. They replied almost immediately, provided a prepaid UPS return label without any difficulty, and handled the matter with complete understanding and kindness. Problems can occasionally happen with any purchase, but what really matters is how a company resolves them. eGency Limited could not have been more helpful, and I would not hesitate to buy from them again. Highly recommended.

Worth it!
I love this! It is way better than just flossing. After I use this a bad taste comes into my mouth which means it's really cleaning out in between my teeth. Plus it gets stuff out that flossing cannot get out. I've come to the conclusion that this was a great buy!

Powerful clean and easy to use
I’m very impressed with the water flosser. It provides a deep, refreshing clean that feels much more effective than regular flossing. The pressure settings are easy to adjust, and the device is simple to use. My gums feel healthier, and it’s become an essential part of my daily routine. Highly recommended!
