Rechargeable! And less mess
The only reason I was skeptical about this item was I was weary of a power cord. But the base is USB rechargeable! So this makes it ultra portable. Works great, many extra tips, and can do my teeth gums and tongue with one tank. Much better than the other one that was twice the price. Switch on handle cord made it more convenient and less mess than ones where you are holding the tank in your hand.  5 stars
