Review (5/5): For the cost, it's pretty impressive
I've had plaque issues for a couple of years, with a periodontist suggesting a $3350 cleaning. I don't know if this item will take care of everything, but it certainly has lived up to the manufacturer's claims so far. Originally, I was going to return the item without even opening it, but that periodontal estimate had me blinking. I'm glad I tried it out, and I'm quite pleased.
