Awkward and didn't work
You have to unscrew the whole thing to fill with water.  I've had many waterflossers that were much more convenient. Mine usually last a year and when I go to buy a new one the one I had is gone. This one I charged completely as I  could tell by the lights. It wouldn't turn on. The other buttons didn't give at all. I chock it up to a failed experiment.
