I purchased your water flosser and although I like the premise of the unit I think the thing should shut off when you remove your finger from the 'on' button. I cannot tell you how many times, in getting used to using it, that I sprayed my entire bathroom sink area with the pulsating spray full of water and mouthwash! I admit I am not the brightest when it comes to using new devices ~ but it seems to me it would not be a bad idea. Other then cleaning my mirror almost every day I am hoping that before too long I will get the hang of it.
I AM A RETURN BUYER. BOUGHT ON SEVERAL YEARS AGO AND WANTED ANOTHER ONE. IT RUNS REALLY WELL AND DOES A GOOD JOB. MY SON IS A DENTIST AND HE TOLD ME TO BUY THIS ONE.
BUT, a "pain-in-the-butt" to use. Waterpik does clean between teeth as needed but loading and cleaning up afterwards not good. Nothing you can really do but it's worth the trouble.
