I have been pleased with my Waterpik and how it does such a great job of cleaning my teeth! I would however like a somewhat gentler pulse sometimes. Overall I am pleased.
It is a very nice device. It is convenient that you can bring it with you when you travel. It is effective and keep my teeth healthy. In fact, this is the third one I have bought. I have use waterpick product for over 10 years. Worth to buy!
The electric one was better - the one that plugged in. This one has a smaller tank so it doesn't last as long before you have to refill it. The flaw in the electric one was with the whip from the tank to the handle. This broke off and so we bought the battery powered version. Don't get me wrong: it works. But it doesn't hold enough water and the handle is not flexible, being hard-attached to the body. I'm not down on it, I just preferred the last one that I had.
