Excellent Value and Good function and design
I replaced my broken major brand name water pick with this one, and although some minor design functions took a bit of getting used to, I do like the performance of this product.  The best thing is the pressure generated is amazing, so much so that I keep it turned almost to the lowest setting, whereas the previous brand was always turned all the way up.  Cleans great.  I have only used this a few times, so have no projection on lifespan, but so far so good.
