Philips Sonicare 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

I tried several cheaper sonic toothbrushes and hated them...they rattled my head even on low. Many had tiny / too small toothbrush heads. Then I sprang for this baby - well worth it! I haven't even gotten to the app or the deep cleaning, etc. But just the basic toothbrush is amazing! I keep it on low for now...which is fine for me and I can really feel the cleanliness when I'm done! I wanted this one also because it has a warning if you are pushing too hard. I'm also pleasantly surprised by the tongue cleaner head / program. All in all, it works really well. And - if you get extra brush heads, no reason you can't share this with someone else in your home.

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.

Great product at a great prime day price. Make sure you register it because these have a tendency to break at the base of the tooth brush applicator. My last two did exactly that, after a couple years. That said- my gums and teeth are so much better and cleaner because of these. I will continue to buy them.

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.

My only complaint about this toothbrush is that it is too expensive, however, after trying other toothbrushes, I canceled my return of this product and decided to keep it. The vibration is effective but not so intense that my hands feel it too much (I have nerve problems in my hands so that was a huge factor for me). I enjoy all of the different settings and use the whitening and gum health settings most often. The tongue care has a specific timer for its setting so I stay away from using that one. I’ve had no issues with the battery life so far as I usually keep it on its charger when not in use. Speaking of chargers, the travel case charger is a great feature for travel! It made packing much easier. It feels like it was made with good quality materials and like it will continue to be durable and not let any water in. I have zero concerns about its durability! My teeth feel incredibly clean- my dentist was very pleased the last time I went in!

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.

Buen cepillo excelente vibración aún en la baja se siente mucho! Variedad de opciones y definitivamente si hay mucha diferencia entre un cepillo normal y uno de estos! La diferencia entre el 9500 y el 9750 es que trae un cepillo extra (cabezal) y la base de plástico para poner las diferentes puntas.

After 6 months, it stopped working! Waste of money
