This is my third Waterpik, the first one was great, and the second one did not last too long. Hope this one will. It does the job like it always has, but this one sounds like my lawnmower. Loud and noise, really kind of funny, it does sound like my lawnmower, even when you turn it off, it sputters. But you can’t beat it for cleaning and flossing you teeth and gums before brushing.
I love everything about the WP-100; The size is just right (does not take up a lot of space) and I like the variety of attachments and speed adjustments. It's very comfortable to use. A great value!
the storage case is a little awkward, you have 6 brushes and only enough room for 4, and is a little hard to get at, but I do like the brushes themselves.
I got this flosser about two months ago. I use it every day because it does a great job at cleaning between my teeth a along my gum lines. It leaves my mouth with a clean fresh feeling. But the best thing is the improved health of my gums.
