So powerful, keeps a charge and love my traveling charging case!

I’ve been a loyal user of the Philips Sonicare DiamondClean toothbrush for 10 years and absolutely loved it, so I was hesitant to upgrade. However, after switching to the Sonicare Prestige 9900, I can confidently say that this toothbrush has completely exceeded my expectations and transformed my daily oral care routine. The cleaning power is unmatched – my mouth has never felt this fresh and clean after brushing. It feels like a professional clean every time, leaving my teeth smooth and my gums healthy. The game-changer for me is the Bluetooth connectivity with the Sonicare app. It offers real-time feedback on my brushing technique, which I didn’t know I needed but now can’t live without. It guides me on pressure, coverage, and timing, helping me brush more effectively than ever. The app is user-friendly, and it’s amazing to see data on how well I’m taking care of my teeth. The design is sleek, just like the DiamondClean, but with even more smart features. If you’re looking for a top-tier toothbrush that will elevate your oral hygiene routine, the Sonicare Prestige 9900 is worth every penny!

Best toothbrush I've ever used. Its expensive but my teeth feel cleaner than when I've tried the lower tier Sonicare models. I really like that it only has 1 button. The models with 2 buttons are confusing and hard to switch modes while brushing. I would like to see new colors. Maybe blue, green or red.

High end brushing with the A3 all in one make brushing a pleasure and combine it with Flaus and/or Slate electric flossers and a water flosser from Remi and the routine is the best it can be. Biggest upgrade is the seamless button so nothing gets trapped in the ridges! The best model brings the best in the app. Significant upgrade over 9300 9500 and 9700. 9900 is worth the investment.

Great toothbrush, but the app needs help, and the "brush head life is too short for the price you pay for replacement brush heads. The toothbrush itself works amazing. My teeth feel clean and instead of brushing in quadrants, it has you brushing in sixths. I actually like this! So from a basic performance aspect, this brush is amazing! But.......the app is very inconsistent. I will be brushing the back of my teeth and the app does not seem to realize this. Then, after I finish brushing, it wants me to go back over the areas that I missed, but I already brushed them. To spend $300 on a toothbrush with an app that doesn't work is frustrating. So, I don't use the app anymore, even though it synchs with my Apple Health app. Lastly, the brush head only lasts about 3 months (if you brush 2 times a day). Replacement brush heads are also very expensive, so this is a bit frustrating. I believe that I can stretch the life of the brush head to 5-6 months, but it annoyingly vibrates after every brushing to tell me that I need to replace the brush head. Nothing that disturbed the cleanliness of my teeth, but it is very annoying. So, again a great toothbrush for your oral hygiene, but if you are buying for the other advantages, buy a cheaper model.

Best toothbrush I’ve ever owned. Leaves your mouth feeling clean, fast charge and easy to connect to app to get all data. Worth the price

I've had a Philips Sonicare Diamondclean toothbrush for 5 years. Recently, the battery on that one started going out so I knew I needed a new toothbrush. I decided to purchase this one because the carrying case seemed much more convenient for travel. I was pleasantly surprised to find this brushed even better than my last toothbrush! It's hard to say if that's because the battery on my old toothbrush had weakened over time, but I've been pleased. I've removed a star because I do think it's pretty expensive for an electric toothbrush, particularly knowing that the battery life is likely equivalent to my last toothbrush (5 years) and repurchasing brushheads isn't cheap. I'm attempting to extend the life by not keeping it plugged in all of the time and only charging it when it is out of battery, though time will tell if this is effective at extending the battery life. That said, it really does clean exceptionally well, and the small footprint for storage is meaningful to me as I travel a lot.

I was happy to find it to work well and as advertized

Works great. The app helps to ensure you spend enough time while brushing with feedback if you apply too much pressure.

The sonic care for me is one of the best purchases of my life. I needed electronic toothbruah which was powerful and does a good job of making my teeth feel clean and these due the job. From the 3 vibration settings to the helpful app to the comfort of the vibration im sure i wont go back to a manual toothbrush again.

Love this toothbrush it does a great job highly recommend

Best toothbrush I've ever owned. Got it as an Xmas gift and it blows away everything else I've ever used. I had an Oral B rechargeable and it was pretty weak and eventually quit working. Then upgraded to a Waterpik Sonic 2.0. 1st one quit working after a few months. Got it exchanged under warranty and eventually the new one broke as well. The Philips is way more powerful and just does a better job. Mouth feels way cleaner afterwards.

This toothbrush is a game changer. The SenseIQ technology really helps me find the right pressure and the midnight blue color looks very premium on my counter. My teeth feel much cleaner compared to a manual brush.

I use it everyday, love the look and feel of it and the charging stand is great. works great

This is high tech. I love the information you can get from the app and how it syncs your brushing to the app and gives you feedback. I also love how the battery is rechargable and has a wireless charging stand it sits on. It's awesome for traveling as well, it has its own protective case. Yes it's expensive but if you invest in keeping your teeth healthy it's a great purchase.

Nice brush, really like the app as it tells me how much I've clean in front and in the back of my teeth. My mouth feels alot cleaner everytime I'm done brushing.

I mean its the best electronic toothbrush. It cleans way better than a manual one. It times to exactly two minutes, I use it everyday.

This is an excellent toothbrush. I purchased the 9700 a few years ago but it stop pairing to my phone. I saw this one on sale during the holiday season and did not hesitate to purchase. I look forward to using it.

It’s expensive but i can justify it for something that i use twice a day everyday. I grabbed this model for the easy charge travel case, because I travel 24/7. Great product slim design works amazing.

Mouth feels exceptionally clean after brushing. Gums feel good also.
