Review (4/5): Hard to rate
This is what it says it is, and it does its little shakey shake when turned on.
But it needs to be used with water which is hard to coordinate. I’m not sure it has done anything - but I don’t know if that’s because I didn’t get my coordination right or if the tool isn’t capable. I know that when professionals use an ultrasonic cleaner my teeth feel cleaner, and I think this is ultrasonic but my not vibrate quite enough. Also, chipping stuff with a point is weird.
To sum up: If you also have trouble finding a covid safe dentist & can splash up your sink area and think this would help, try it. It might not do everything claimed but it is a water tolerant rechargeable pointy tool that’s not heavy to hold.
