Review (3/5): I Like the big reservoir, but I . think it lacks power.
I keep this water pic in the shower. It has a giant reservoir which i fill with mouthwash. It can be a little cold for sensitive teeth but you put it in your mouth before you start it up. Once you turn it on, you have three speeds which I found were not very strong or at least not strong enough to really push plaque out from between my teeth. I use this as a way to get my mouthwash in hard to reach areas of my mouth but won't use this in place of flossing.
