Hard to rate
This is what it says it is, and it does its little shakey shake when turned on.<br /><br />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.<br /><br />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.
