Super buy!
I really like it. Up to now, I bought 3 of those. At first, I tried it and love it so much that I bought 2 more for my relatives and they love it. The valve is metal and did not want the plastic valve. it has 3 brush and 3 flossers, so I don't have to share mine with others. And it is inexpensive compared to others, especially the electric ones which are set for failure by design.
