Title: Stopped working after 7 weeks.
Review: I was quite excited to get my first Waterpik at the recommendation of our dentist. It was really clearing up my husband's problems with his gums and both of us had fresher breath. Unfortunately, the unit stopped pumping water after only seven weeks. We used it twice a day. I returned it for a refund and purchased the less expensive version with the open top. It's been several months now and the new unit is going strong and was WAY less money. I recommend people just go with the cheaper model, despite it's less "sleek" appearance.
