I have one of those because my teeth sucked and my dentist told me I need to go electric or I’ll probably get gum disease. So now it tells me whenever I should switch to a different area of my teeth. It’s really much better than manual brushing in terms of how polished your teeth get. I don’t think the “AI” part works very well, not even the pressure sensor. I wouldn’t really need it either, just tell me when to switch. It’s also a privacy nightmare but I’m kind of in between giving away my data or risking that my teeth will fall out, so it is what it is.
