Review (3/5): Clumsy
I had a Waterpik for several years that stopped working. I replaced it with this model. The design is not as ergonomically successful. I’m not sure what the difference is, as I don’t have the old one for comparison. It seems that the wands are shorter and fatter, which make it more difficult to manipulate in my mouth. The old model had a pressure control for water release, this one has a switch that doesn’t operate as easily as you turn the device inside your mouth. If you still have a working older model, I would not recommend replacing.
