Philips Sonicare - DiamondClean Smart 9300 Rechargeable Toothbrush - Gray

I'm a member of Mensa and I can't figure this thing out. It gets my teeth clean, however I can't find the documentation regarding which of the 3 types of bristles match with the 5+ modes. I realize there is an app, however I don't want my phone in the humid bathroom in the morning as a brush my teeth. I'm sorry I upgraded from the simpler models.

I've used Sonicare toothbrushes for many years and I must admit, I like my newest one the best of all: Philips Sonicare DiamondClean Smart Sonic electric toothbrush with app HX9903/21. This toothbrush is so thorough at cleaning and whitening that I don't need any other products to keep my teeth clean and bright. It's a high quality toothbrush -- well made and easy to keep clean. The brushes themselves are larger than the ones I used to use, and they not only clean my teeth but feel good on the gums. I am very happy to have invested in a high quality toothbrush such as this one.

Very frustrating and unfortunate to spend 100's of dollars on a tooth brush where the iOS application crashes frequently and/or frequently won't connect to the toothbrush from the iOS application. iOS developer get crash reports of applications and it seems that Phillips doesn't look at these to discover why the application crashes in the middle of a brushing.

I've been pleased with the toothbrush and its many features. However, I am confused about when to replace the brush head. The very brief brochure describing the features only mentions that an icon will appear when it's time to replace the brush head. There's no mention of what the icon looks like. My brush head is getting worn but I haven't seen any icon other than the "Clean" light flashes when I finish brushing, but I don't know if that's the one telling me to change the brush head. Also the battery light goes on and off when it's time to charge, but again that isn't mentioned in the brochure, so I just figured it out intuitively.

I had a diamondclean for a couple of months that stopped working properlt adter a drop in the sink. I dis not register it for warantee protection and was a little disappintef that it was so succeptible yo famage by such a little mishap Nevertheless, i liked how it cleaned and bought another I find the iphone stnc business to be nothing more than a silly gimmick, and find your repeated prompts to synch my brushjead on the phone to be annoying Also, i liked the old brush's four X 30 second timing prompt cycle The new one seems to have six or more 20 second prompts It seems to be irregular, and one stopwatch experiment the cycles lasted for over 2.5 minutes. That is too long, and the multiple changes are a distraction. I find myself losing track and wondering, was that 4 or 5? Then shutting it down. 4 cycles - and two minutes seened easier to deal with and 2-minutes seemed plenty If there is a way to change this, let me kno
