I bought my wife a WaterPik, and this one for myself, and both are great! In fact, I think the water reservoir lasts longer in this one. It comes with many heads and is of good quality.I really like its three-second crescendo function, the pressure gradually increases, it is very good for the gums, and it feels very comfortable. Anyway, this is a good product and I recommend it. Especially because it is so much more affordable than the name brand!See full review
