Title: doesn't work
Review: After using the cordless travel waterpik for years, I thought I would try the plug in kind. That was a mistake. After the first few uses, it stopped working. I turn it on and hear the unit whirring, but no water comes out. I was going to return it but had such faith in the product, I didn't keep the box. I ordered 3 more cordless waterpiks and although charging them is a pain, at least they work and the spray is powerful. Now, if they could just make a purse-size cordless so I can carry it everywhere.
