The only complaint I have is that there should be a design improvement. The lid should be attatched with a hinge. Almost everyday I fumble with it and inevitably the lid falls in the water I just put in to floss with. very frustrating. It would be a simple fix and wouldn't intrude on anything that I can see.
I purchased this about a month ago to use as an alternative to regular flossing. I have dental implants and there are a couple of places where it is nearly impossible to get floss. The Water Pik reaches these areas and makes it possible (and comfortable) to remove trapped food particles.
i bought this for my husband I have had one for apox 2yrs we had a hand held one that he used and battery went dead I had the bigger one so I bought him one to like it alot
