This is a good product. It does the job nicely and quickly, flushing out any leftover food particles stuck in your teeth. I'll mention one thing that I won't call a complaint; more a suggestion. I find the reservoir cover to be slippery when wet. If the cover's edge were serrated all around I think this would prevent it from slipping out of your hand.
I've used electric toothbrushes for years but my dentist and dental technician suggested adding the Waterpik to my daily brushing routine. I probably should have done this years sooner but can now see the additional advantage of using the Waterpik.
I bought this aterpik about a month ago. As well as my Hygienist berating for not regularly flossing..., the TV advertisements made it seem a good idea. Early days yet - but will I fall off the cart like I did with my exercise and weight training?
