Motor died prematurely, in my view.
on February 9, 2015
Bought in April 2013. It slowly died in February 2015. I turned it on, the motor started, and the rpm slowly went down to zero. It was not the switch. I couldn't check more.
I bought this to replace a unit I had from the 1970s (or before). It was still working. I bought this because it looked prettier. I now wish I had kept the old one. Sadly, I simply discarded it--I can't keep everything. Since the Waterpik idea is so good, I guess I will just have to buy another one. I will check around first to see if there are close competitors.
There are smaller things I didn't like. The shape of the plastic nozzle seemed not as good. I heated it some, bent it some, and it was much better. Also, it leaked a little out the bottom when using, so that there was a little puddle under it when I turned it off. This is really not a problem--water on counter surface is common. I haven't researched Waterpik. My guess is that they are a very big American company that has a very good product idea and that grew to be very large. If so, they have no excuse for not doing a lot of research to improve their product. My experience with this one is that they made it worse.
And there is another thing about the design. The nozzle and nozzle handle, at the end of the plastic hose, did not fit well into the holder after use. After a while, the plastic connector on the end of the hose popped out of the handle. As near as I could tell, it was designed to snap back it. But it wouldn't stay in well. I put a heavy rubber band around it and that worked until the motor died.
