Negative Positive
Title: a very poor waterpikr
Review: This model is so much more quiet than the other older models. Amazon's price is much lower than retail stores (at the time I got it). It seemed Ok at first, but after a few months it lost power then finally stopped. Never buy this model (the blue one)... get the older moder (white one 70). I have two and they have lasted for years. I use it after each meal.
