Philips Sonicare DiamondClean Smart Electric, Rechargeable Toothbrush for Complete Oral Care – 9300 Series, Gray, HX9903/45

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!

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!

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!

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!

This electric toothbrush arrived promptly after ordering in perfect condition in its commercial packaging. I had been using a previous version of the Sonicare 9300 for about two years when it started rattling when it started and became impossible to use. I liked it because it really cleaned my aging teeth well but it seems the shaft might be vulnerable to vigorous use. This new one works very well but I notice that the warning light comes on sooner than the old one telling me to ease up on the pressure. Maybe this will make this one last longer for the price I paid.
