Review (4/5): Good value
Arrived in 2 days to Hawaii, quality stainless steel dental pick and mirror, this calculus remover apparently has five speeds but doesn't indicate in the instructions what the different speeds are for nor even how to adjust them. Questionable whether or not this kind of device can remove stains but it definitely removes hardened plaque and calculus without the potential hazard of cutting yourself with the manual tools. I will definitely use this device on a regular basis to maintain healthy teeth and to travel with it. Half the price of other brands and appears to be identical.
