My husband and I have been using Waterpiks since the 1970's. They have always been quality products and we've only "upgraded", never had a flosser go bad or wear out. Our newest model (WP112 - Ultra) is by far the best, feature-wise. The profile, size, color (black), adjustability of pressure, selection and ease of changing piks, reduced noise level, and handle storage makes this one just about perfect. Wakterpik will have to step up to improve on this model.
Nice machine, but for me it just wasn't what I was expecting and without features I wanted. I returned and bought the WP-670 online. And am pleased with it!!?
I love this! It works great and does the job! Love the different pics that come with it as well I definitely feel the difference since I started to use it.
I've been using this for several weeks now and really like how clean my teeth and gums feel. If I could change anything...I would put the on/off switch on the handle. Yes, the handle has a pause button to stop water flow...I would rather have a one hand operation.
