I bought the Waterpic as replacement for a similar tool of another brand. The function is similar, I like very much the cleaning of the gaps between my teeth and Waterpic dos it perfect. My old instrument failed after just some month mechanically but I hope Waterpic will do it much longer, if yes, it is perfect!
I bought my first unit many years ago and used it just about every day. It finally died and now I am on my second unit. My teeth tend to catch every kind of food, and this product cleans between my teeth extremely well and is also very beneficial to my gums. It has a lot of power! I take it with me on vacations also because it is so portable.
