Query: It works great for 2 months, that was it!

This item is a very neat idea, portable and rechargeable, although it doesn't hold much water in the tank, I don't mind filling it up twice every time I use it. The jet stream is very powerful, it does an excellent job of cleaning between my teeth, it certainly feels cleaner than flossing. For 2 months or so I thought I had bought the best consumer product ever, until one day it just stopped working. It turned out that the socket for the charger was completely rusted. My advice is DO NOT buy this product, wait for WaterPik to come up with a better model!
