Be aware! Poor quality, definitely not waterproof, expensive mistake.
29 November 2017
My Philips Sonicare HX9111/21 FlexCare Platinum Electric toothbrush (UK 2-Pin Bathroom Plug). Considering this is a toothbrush, you would think it would be waterproof, it isn't! Moved away from Oral-b but regret it. This has lasted just over 12 months. It keeps starting itself at all times of the day and night. It looks like it is not waterproof, there is evidence of mild corrosion around the on/off button and the waterproof gaiter at the tip. I have googled problems with the brush and a great many users are reporting similar issues, so be aware, it is a lot of money for such a poor quality item.
