DiamondClean Smart 9500 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 5 Brushing Modes and 3 Intensity Levels, Black, Model HX9923/11

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.

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.

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.

Definitely the best thing I purchased on cyber Monday sales! Toothbrush is great it brushes the teeth really well..love all the different cleaning modes it has especially the deep cleaning and whitening teeth mode! definitely prefer electric over manual for sure! Vibration is not overly loud or excessive..and since purchased haven’t had to charge it yet! Battery life has been great so far..worth every penny invested for it

Makes you enjoy brushing your teeth and does an excellent job cleaning

Absolutely love this toothbrush! Our dentist recommended we use Phillips Sonicare brushes and at first I was a bit skeptical. I order this about 1 year ago and waited to see how much I liked it before writing a review. After using it for a year, I'm not sure why I never checked one of these out before. Ergonomically, the base of the unit fits well in my hand and is easy to maneuver. The buttons are placed in great positions so I can change the brushing modes or intensity levels easily on the fly. I keep it on a shelf mounted in the battery charger at home, but I have travelled with it a few times and the battery holds a good charge for more than a few days easily. I've never had a situation where I've taken it with me and had it run out of battery. It cleans very nicely and isn't too bulky to have any issue reaching the back molars and has great maneuverability while brushing. I like the fact that it's not very loud as far as noise, and it has convenient 30 second notifications to let you know how long you've been brushing. I typically do one quadrant for 30 seconds for a total of 2 minutes, so it's nice to have the 30 second 'buzz' go off and let me know it's time to move. Two of the coolest features about this electronic toothbrush: (1) - the pressure sensor that let's you know if you're brushing too hard. It's easy to see the light come on when I tend to put too much pressure on the head. (2) I use it in the shower so it's nice that it's mainly waterproof (even if it's not sold as that in the description) but I have been using it in the shower for a while and it's not had any issues. The travel case is nice to have when you need to pack it up and head out on the road. I stay away from home about 4-5 times a year for work and it packs up really nicely and the case obviously keeps it protected. If I had one complaint it would be the unit cost and the replacement head cost. When I first looked them up, I thought the price was crazy!! But it's held up and continues to be my favorite toothbrush of my life, and I've had many in my 50 years on this planet. If you're thinking about getting an electronic toothbrush, this one definitely delivers.

I bought this toothbrush as a replacement for my last one - same brand that I purchased over two years ago - love this toothbrush! It was on sale so good value

Amazing product, not the best process with shipping however could've just been me.

I purchased the Philips Sonicare DiamondClean Smart 9500 on September 11 for $273.61 SGD ($203.48 USD), and it has completely failed after just two months of use. The toothbrush head holder is loose and doesn’t hold the brush properly, while the body makes a loud, awful rattling noise. This is unacceptable for such an expensive product.

After 6 months, it stopped working! Waste of money

Je l'adore
