Quits working after a month.
The unit has a few seconds delay after it is turned on. One charge last about a month for a once a day use. It is convenient for traveling. However, it quits working 3 days after return window is closed. It just quits! I thought it needs charging so I left it charge until the green light comes on. But it still doesn't work. Now I am stuck with a non-working flosser. Too bad it doesn't last. What a shame!
