Review (5/5): Compared to the rest this IS the best....
This is the best....you can even easily empty the reserve....where the water is stored and make sure that no mold etc forms....I had others.....many more expensive but this one is at another level.....it is perfect. No issues except when I get done doing the deep clean along with my sonic care....I look in the mirror and wow....see such a difference....This is not a paid ad...this is just so great had to share it will you all....go for it....
