My partner once received a toothbrush like this. I enjoyed the instruction manual's image showing someone using their phone instead of the mirror: https://imgur.com/a/VfT2WEl
Of course, it could also be a replacement mirror, but given that there are tiles drawn next to it and the phone holder is a suction cup on what vaguely looks like it might be a mirror, I doubt the phone is meant to be a mirror. Or am I missing the point here and is the message simply that one should be looking in the mirror rather than their phone while brushing teeth?
Here’s why: You need to look into the phone while brushing because it uses the front camera to do its thing. Pairing bluetooth and opening an app every morning is way way too much work for a 2min task. Screw that
