Customers are saying

Customers often highlight the DiamondClean Smart Electric Toothbrush's superior cleaning performance and the variety of brush heads included for different oral care goals. The long battery life and helpful app are also appreciated, along with the sleek design and pressure sensor. A minor drawback is that the travel case does not function as a charger.

  • Works Well Until It Breaks

    I'll be on my fourth soon. I bought one of these years ago, worked great, broke under warranty. Got a second via the warranty, it lasted a while longer (maybe longer than the first). Bought a new one and it just broke within the last week after a little over a year, so I should be able to warranty it. They're worth it to me, but also keep your purchase info because there's a really good chance you'll need it.

  • December Dental Exam

    The Sonicare yhat I purchased in November 2024 is an excellent tool in maintaining strong, healthy teeth. My exam in December revealed no issues. I believe that with the daily care I follow with the Sonicare toothbrush, my teeth are cleaner, and there is no build-up of plaque. The automatic timer during brushing is a positive as this alerts me when to move to another area to clean. Excellent product!

    Great toothbrush. It seems to vibrate faster than my OralB, but that was getting old, so… But I would recommend as my teeth and gums feel great and I don’t remember the other having that effect.

  • Cheap Trash

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This toothbrush is cheap and loud. In addition to the sonic noise,there is a loud motor noise. My last Sonic from 10 years ago does not make that additional noise. Quality of Philips has obviously diminished. I would not recommend this item to anyone. Further, I have spent over 1 hour talking to people from around the world, and I continue to get conflicting information. I hope I am able to get my money back for this piece of trash.
