Easy to use
Had mine a couple of years now and I’m still impressed by how easy it is to use. It removes all tarter build up, nicotine and coffee stains in minutes. Since purchasing I haven’t needed to see the dental hygienist as I can keep on top of cleaning myself, so this more than pays for itself and there is no discomfort or pain unlike when the hygienist cleans your teeth. I would highly recommend you purchase one and see the great results for yourself. You won’t be disappointed and when fully charged you get numerous uses too.
