So far, it's a great tool... a little awkward to get used to, but overall, we're liking it.

I am happy with my new water pik because it is smaller and takes up less room on the counter. The battery lasts longer than I expected. The pressure and the nozzle are excellent. I need to fill the reservoir two times due to its smaller size, but I am glad to do that in exchange for the space needed.

Excellent pressure and three head options but the best is that’s it’s cordless and the battery life.
