I bought an oral B electric toothbrush and love it. Cool thing? It came with Bluetooth which connected with an app and had some nifty features like position detection and an automatic timer. Then I accidentally did an update for OralB and suddenly, the brush I paid over $100 for six months ago is unable to work with position detection without the camera, and I need to update my toothbrush(ie, purchase a new one) Seriously?!? I can deal without position detection, but it’s terribly annoying that it does not automatically start the timer when you turn on the brush with OralB open. You have to turn it on, tap ok, tap brush now, and start brushing in ten seconds, or it says it needs to restart and you have to tap ok, then brush now AGAIN. And if you have the brush on, you have to turn it OFF, then hit brush now, then it starts the timer from however long you’ve been brushing….. well, it’s annoying. The older version was way better. I was also upset that all the data fro the six months I had been brushing was lost, and the data reset starting from the date of OralB update. Just a PIA. OralB is ok otherwise.
