Had a Waterpik in the 60's - was I a pioneer? I can therefore attest that the Waterpik has come a long, long way and I'm still getting "acquainted." I'm just beginning to experience its beneficial possibilities, and I definitely envision a positive Waterpik future! So glad my dentist recommended, as I didn't even know it was still in existence.
I have had a couple of problems with the pressure when trying to use one of the attachments which it comes with - I tried cleaning it with hot water and this seemed to work but I don't think I should have had this problem I've only had it around 6 months.
Bought this after my Dentist recommended it since I have a difficult time flossing between my teeth. Recently got a bridge, the space between the bridge and teeth is so tight the floss shreds. The Waterpik works great and is easy to use. The higher settings are strong. I haven't had any problems with the pause button sticking yet. I wish I bought one years ago.
Overall I really like this product. The only 2 design considerations that I was unhappy with were: 1. Although it is great that I got all sorts of attachments, the case cant easily hold them all. 2. It seems like it would have been more intuitive if the button you held on the waterpik was to initiate the stream rather than interrupt it, meaning that by default, the water is shooting out and you have to hold the button to stop it. Seems like it should have been the other way around.
