This is definitely one of the best investments I made in my dental care! I was skeptical about the app and all the bells and whistles but I'm so glad I took the chance. I dont always use the app but I've learned to brush better and it's useful as a guide. Even a little fun! Yes, it is quite pricey and I'm not really one to spend so much on a toothbrush but this one was worth it.

This brush has continued to impress me over the last couple months. Great cleaning and whitening modes, charger & case, and premium feeling build. Makes brushing a joy and Leaves you feeling like you just went to the dentist. Great product. The app isn’t perfect, but functional and not material to my overall experience. Love this brush!!

I would never know I would buy a toothbrush at this price in my life but I'm happy I did. I have owned 2 other sonic care Philips toothbrushes but this one is so far superior. I enjoy it, the app for it is very helpful. I would recommend it over n over

My family has been using Sonicare toothbrushes for years, and this model has been excellent so far. While I don’t really have any way of knowing exactly how well it cleans my teeth beyond looks and feelings, my regular check ups at the dentist have been problem free. Overall it’s an easy to use system, and great for anyone looking for healthier teeth.

Best toothbrush I've ever owned. The charger is the actual glass, comes with different heads so the base can be shared. The changing heads are even have different color bands so you don't mix them up. When I'm finished brushing my teeth it feels like I just left the dentist from a deep cleaning.

I was on the fence about getting one of these for quite some time but finally decided to go for it. The app that can be used with this brush is great and I feel has helped me do a much better job brushing, my teeth have never felt so clean it's just as good as when my dentist does my cleanings!

Great electric toothbrush with fast wireless charging, super long lasting battery life, and great cleaning power. One star off due to its high price.

Best electric toothbrush on the market--bar none. My teeth feel like I just received a dentist's cleaning and polishing after every brushing. Our family has owned several of these incredible toothbrushes from Philips, there is no substitute for the DiamondClean by Sonicare.

Honestly I don’t think it was crazy to spend this amount of money on an item that I use consistently twice a day for the rest of my life. It cleans well and I love the features it has. Also like that it shows how well you cleaned your teeth. Honestly enjoy brushing my teeth now. Great product.

Phillips makes excellent tooth brushes and this is no exception. It is easy to get caught up with the different types of brushes. What brush to buy is always a question.
The older brushes gave a notification when a minute transpired. Each quadrant was a minute. It appears they broke this out into eighths. This is too complicated. I still try to brush based on four areas. It sometimes appear as if it stops before I am done. This should be easy. Why did Phillips turn brushing into a convoluted chore?

Great toothbrush. Automatically turns off after 2 minutes so I know when to stop brushing. Very easy to use and clean. Love the app that tells me what areas of my mouth I need to brush more. Everyone should get this toothbrush.

Love the power and settings for different cleanings this brush offers. Will see how durable it is. This is my 2nd unit. The first brush lasted me 4 years until the brush tip broke off. Im hoping that is a one off issue.

I’ve always wanted an electric brush. I did tons of research before purchase. I am blown away. Worth every penny. I understand the hype. My mouth feels and looks soo much better. My dentist even noticed and I brush regularly but it’s just soo much better than a manual brush. I highly recommend this brush to everyone on the planet
