Review on Audio toothbrush Philips Sonicare DiamondClean 9000 HX9914/57, black/white by Guan Yin ᠌

- A bunch of unnecessary features that are obviously overpaid for, such as a chip in the nozzle that allows the brush to track the duration of its use. - Expensive nozzles, more expensive than Oral-B, one and a half to two times. - Different brushing modes differ, according to the sensations, only in duration, so I use only Clean. - No carry case. - Toothpaste is clogged in the crack near the buttons. - Stupid app that you only need to ate the firmware once. Yes, yes, the 21st century - a toothbrush requires a firmware ate. But you can not ate, it works well enough. The rest of its functions are stupid: a crooked store, a crooked connection with support (the "Write to chat" button is blocked), and for some reason it expands to full screen.
