Review title is For the money and portability nice choice [SEP] Ok, its not gonna be as powerful as an electric water pik but I didn't expect it to., I do, however, think it has plenty of force to push food out between your teeth, is nice and portable and for the price seems well made. The directions say you can use the unit with mouthwash. I use Spry oral rinse in the chamber which contains xylitol to further improve cavity and bacteria prevention. All in all a good device - inexpensive- efficient and most of all very portable. One note - DO NOT remove the sticker on the side of the unit, the directions say to, but who ever designed the glue wasn't aware your suppose to remove it. You'll end up with a gooey mess on the side - I had to put tape to cover it up
