This is the third Waterpik we have purchased through the years and we still thoroughly enjoy this product because it works so well! This latest waterpik is a tad bit louder than the previous two we purchased, however, that is the only flaw we can come up with for this product!
I bought this product with a lot of doubt, but after I use it for a few weeks I found it effective. I use salty water or mix the water with Listerine products and I found it effective. But more accurate review will be when I go see my doctor. The only downside is that it is a bit noisy.
I recently purchased my second Waterpik -- WP -100. The first one worked well for about two years, until even the highest settings resulted in minimal water flow. Still, in today's world, this is a product worth the money.
I bought this waterpik a couple of months ago. I was having a problem getting food out of my back teeth. My teeth are really close together. It works perfectly. So happy that I bought it.
