    Did a lot of investigating before buying this toothbrush. It’s my first electric toothbrush and so far I love it. Cleans my teeth a lot better than a regular one. The only con it’s the price

    I bought this for my son who researches everything and he was set on getting this item for Christmas. Well he is very pleased with the toothbrush so far and we would definitely make the purchase again. I thought it would be crazy to spend so much on a toothbrush but if it saves money and time on dentist’s appointments then it will be worth it.

    This toothbrush not only gives you different brushing types, you can track how effective you are brushing with the Sonicare app. The app tells you if you are brushing too hard or too light and where you need to spend more time. It tracks your brush head life cycle and you can order brush heads from the app. You can personalize gum care, teeth whitening etc. a true smart tooth brush.

    What a fantastic toothbrush. I originally had a older model that eventually gave out and tried a TAO brand for a minute. That brush did not last not even 4 months. I reached out to customer service and only silence was heard back. So I went back to Phillips. Since the first brush, I cannot say enough how wonderful it has been. I highly recommend it to everyone.

    Do you only get that once a year dentist clean feeling once a year or so? Well I'm here to tell you that this little beauty can give it to you every day. I was completely floored! It tickled at first but after the first use you get used to the cleaning vibrations that this toothbrush puts out. I highly recommend buying one, it will be the last, best toothbrush you'll ever buy.

    This thing is so incredibly loud, so loud my next-door neighbors thought I was using a vibrator twice a day in the bathroom. It works well and has a really cool charging system. The additional bristles are incredibly overpriced and makes me want to use a normal toothbrush. I would recommend if you’re terrible at brushing. PROS: Easy to use Great for lazy people Cool charging CONS: Louder than you think Expensive attachments Settings are just a marketing scheme

    Definite upgrade

    Upgraded from a diamondclean to the newer model and for the little extra dough it works wonders! Comes with three toothbrush heads to help with different areas of oral health (gums, whitening, plaque buildup) it’s easy to sync to the app. You literally open the app and turn on the toothbrush, pretty dang easy! Plan on buying another, the teeth whitening part of these toothbrushes makes it worth it for the price alone

    Been using sonicare for 22 years. Went from the cheapest to whitening to flexcare to this. The previous upgrades were a big difference. The vibration speed etc. Coming from flexcare ($99) to this ($150), not so much. Much better battery and construction though.

    The Best Toothbrush That I Have Owned!

    I absolutely love this toothbrush, because the app helps you brush your teeth perfectly. I also have gum issues that this toothbrush helps me take care of. I also love that both the brush and the app let me know if I’m brushing too hard or moving the brush too quickly. Definitely the best toothbrush that I’ve ever owned!

    Best toothbrush I have ever owned. Was hesitant due to the price, as I’ve never had a smart toothbrush but after using for a few weeks I’m super happy with it and will never go back. Love the features and ease of use, pairs via the app and phone easily too. Bought one for me and the wife, we both recommend!

    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.

    I’ve used this toothbrush for a little over two years now and it still holds strong. The traveling case is sleek and low profile enough to fit perfectly in my travel bag when on the go and as long as it’s fully charged the day before it can last pretty much the whole week. 5 Stars!

    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 have not had my first dental visit yet after getting the toothbrush. My teeth do feel cleaner than with my regular toothbrush. I cannot say if this brush is better than a Cheaper version. I also don’t like the vibrate feeling when I’m brushing.
