Very reliable and sleek product
Very useful and better than most of the products which are double than its price.

Good but too soft
It's a good flosser but very gentle. So if you are used to something with more pressure then avoid this. Good for beginners maybe or someone with sensitive teeth and gums.

Doesn't work as a water flosser
While it does try to floss, it's just not strong enough to clean anything. The water capacity is also not large at all. It's medium at best and gets empty really fast. It's cheap, and the price is tempting, but it just doesn't work.

Poor quality product without warranty
The product stopped working within 2 months. I tried to recharge it, but without success. I checked with Amazon, and they informed me that there is no warranty on this product.

Broke in 2 Days – Water Leaking Everywhere!
This product is absolute junk. After just 2 days of use, it started spraying water out from the nozzle base instead of working properly. The quality is terrible, clearly very poorly made, and it feels like a waste of money. Totally unreliable and not worth buying. I would never recommend this item to anyone.

Not Powerful Enough
The product I received doesn’t have the Coslus branding on as pictured in the listing. I previously owned one branded Coslus, and it was great; super powerful, perfect amount of water in the tank and the battery lasted forever. This one looked slightly different so I just assumed it was a newer model. This is some poor weak version, I can still feel things between my teeth after I’ve used it. It’s really not powerful at all - I’ve seen reviews mention that the pressure pops the spout off - I don’t know how, there’s no oomph in this, at all. Threw the box away as I received it in the afternoon and didn’t use it until the evening, so don’t imagine I’ll be returning them - they’re probably suitable for children but the previous model I had was so much more powerful - therefore I’ll be looking for an alternative brand.

This works great - I like the position of the on/off button so it's not always pressed by mistake, spraying water all over the place. There are different buttons for strength of the water stream. Also, there is a plastic plug that you insert into the charging port so it doesn't accidentally get water in it when the tank is filled or during use. I recommend this.

We got my daughter this water flosser right when she got her braces on. She wanted a hundred dollar one and I said not after we just spent 6k on braces. I found this one and she loves it. Water flow is perfect and no malfunctions on buttons.

I bought this about two months ago and accidentally dropped it and smashed it. I replaced it with the Oral-B version and the Oral-B one is well worth any extra price. This one is decent, but the oral-B is perfect.

My dental hygienist recommends this particular brand of water floss, and I am profoundly grateful. It features three different speed settings and five interchangeable heads. The rechargeable design is an excellent feature, and I also appreciate the variety of color options available. 🌸

Easy to use. Works as intended. Teeth feels clean after. Still using massage mode and it's pretty comfortable for beginner.
