Review: Great toothbrush if you know how to use it, it can be repaired! - This is the third one I have owned. I read the reviews and it seems hit or miss. After 10 plus years of using the black diamond here is what I can tell you. If you press too hard (apply to much pressure) while brushing it causes slop in the sonic arm that the brush head engages. This arm has a gap set inside the handle and is held in place by a small screw. You do not need to push at all on the brush. If you do and the arm is wobbly and you don't feel the sonic motion, it can be fixed pretty quick. There are vids on YT that show you how to reset the gap and tighten the screw step by step, note use some locktite when reapplying the screw. There are also vids that show you how to replace the battery and actual upgrade it!! On the first 2 I bought, I applied too much pressure and was frustrated with the toothbrush. So I took it apart before trashing them and stumbled onto how to repair the $300 toothbrush. Phillips was of no help either. So you may ask why did I continue to purchase and repair the black diamond? Fair enough! Its because for 10 plus years I have had consecutively perfect dental appointments! Everyone of them! Very minimal cleaning, in and out in about 30-40 mins each visit and told keep doing what you’re doing. So its pricy, you need to know how to use it properly, Phillips customer service is ehhh, can be repaired and most importantly it WORKS! All three are still charging and working flawlessly! I have one for home, one for travel and a back up. Had I known you could repair them I would not have bought the second one. This one was on sale and ridiculously priced so I bought it.
Review: Best toothbrush ever! - This has basically made brushing my teeth a game and I’ve become so much more consistent. My hygienist noticed a huge difference after I bought this. It encourages you to brush more often and gives you tips when you’re doing it wrong with too much of a brushing motion or force. Very easy to use and keep charged because it comes with a little cup that it sits in to charge. Usually takes 2 minutes to brush your whole mouth, sometimes a little longer if you miss some spots and it lets you know where you missed.

### ⭐⭐⭐⭐⭐ Beautiful Investment to Myself
*by M***R on July 18, 2025*

I had always used a manual toothbrush until my dentist recommended I get an electric toothbrush due to some gum disease onset. I asked the dental assistant which they recommended and she said everyone on their office has the Phillips SonicCare line. I immediately bought the 4100 a few months ago while I did more research and the 4100 did a good job. I’m Amazon Day when it went on sale, I upgraded to the 9500 because of the gum health and white teeth features and it appeared to be much better quality. This toothbrush far exceeded my expectations! It’s powerful and amazing! The different brushes are so nice too. It feels luxurious. It cleans and brushes much different than the 4100 model. I love the travel case and will use that. The glass to charge it in is really cool and pretty. It’s beautiful! While not cheap, I got a great deal and look forward to my next dentist visit. I’m confident it’s making a big difference and is an investment in my oral health and because gum health affects other health conditions, this is a great investment and gift to myself overall. Worth every penny.
