The best there is on the market!
Highly recommend! The quality and comfort this toothbrush provides is beyond my expectations! It’s been easy to use and provides a better clean than any other brush (electric or standard) I’ve ever tried. It is easy to travel with considering it has a travel case that comes with and the battery lasts a week or more on a single full charge. Definitely worth every penny!

Phillips Sonicare 9300
This is a very good product recommended by my dental team. It is very easy to use and makes my teeth feel very clean after each use. It is ergonomically designed and fits well with my bathroom's decor. Good job Sonicare!

Great toothbrush for managing oral health
This is my first Phillips toothbrush, and I’m really enjoying it. While it is quite pricey, the payout is in minimizing issues at the dentist’s chair. I really appreciate that the app helps manage time spent in each area of the mouth, pressure, and scrubbing. It also enables you to flag problem areas requiring additional attention, reminding you to take extra care there. After reading some of the comments regarding concerns with charging via a cup, I was also concerned regarding how this may look. That said, I was surprised to see that there is an alternative option for a separate charging stand which is smaller in size and enables the toothbrush to stand upright. I prefer this option, and think it looks very clean and organized. I will second that the travel case does not charge the toothbrush itself. However, I consider this an extra luxury (an electric of toothbrush of this size is NOT one I would have ever considered “travel size” in the first place - a bit of clunkiness should be expected). I would be just as satisfied to pack the charger separately or temporarily opt for a non-electric toothbrush for lengthy travel. All in all, I’m very satisfied with the quality of this toothbrush.

Wonderful toothbrush
I love them. I’ve had it since I’ve had one since they were invented.

Avoid the 9300 Series at all costs!
This is my 2nd DiamondClean Toothbrush. The first one lasted almost 10 years and worked like a dream. This one has a problem with the design. I bought it in February and within a couple of months, it stopped vibrating and instead, just spasmed. I contacted Sonicare and they sent a replacement. Within a month of getting that replacement, it started the same behavior where it would not function correctly. It is now a countertop decoration. I love DiamondClean, but not the 9300 Series. It has a design flaw that my previous toothbrush didn't. Unfortunately, it was a waste of $200 and I am now using an Oral B. I would have LOVED to have stayed with DiamondClean as they leave you feeling like you just left the dentist every single morning. But this Series has a design flaw. DO NOT PURCHASE THIS PARTICULAR SERIES!

Great performance, questionable durability
I love this toothbrush, but it keeps breaking every 2-3 years. I keep ordering new ones because I’m addicted to the fresh-from-the-dentist feeling of clean. I feel bad because each time I throw away a bunch of accessories I don’t need because they last a lot longer than the toothbrush itself.

Best Investment EVER
If you don't use a Sonic Care toothbrush, you are missing out on life. This is the best invention ever. I look forward to brushing my teeth and often brush several times a day (with my favorite toothpaste - Arm & Hammer). I never have plaque or cavities. It's the BEST!

Dentist clean.
Was using the diamondclean classic, this version is totally different. The high intensity gets your teeth clean feeling like after the dentist. It's pricey but we'll worth it.

Fabulous! I am a smoker and this toothbrush has made that not at all visible on my teeth. Changed my cleanings at dentist from every four months to every six months. WELL WORTH IT!

Diamond clean is a beautiful brush. Connects to iPhone app to record & monitor your session and gives pointers to improve your brushing. I had an OralB brush before. I like this better.

This is a replacement of the first one which lasted 3years. I decided to buy it again because my hygienist couldn’t stop to mention how wonderful and healthy my gums were since I used my Sonicare. I wish you the same with your electric toothbrush.
