Not as advertised
Upon receipt; followed all instructions; proceeded to use.<br />This thing does NOTHING to remove plaque, calculous, stains.<br /><br />Was extremely disappointed-- have not been in for cleanings during Covid, was hoping to remove some of the damage done-- but did not think it'd do all (dentist is best for a deep cleaning)-- unfortunately-- this thing does absolutely NOTHING but vibrate.  Buyer Beware!!!
