Lasted 30 Days
Stopped working after 30 days. The device would turn itself on even when switched off. We never dropped it or left it on. We can't return it because our return window has passed.<br /><br />Update: DH Express read this posting and gave us a new water flosser even though the 30 day return window has passed. It's working well and there are no complaints with the replacement.
