Review (4/5): Works well - one issue.
Very nice for travel. Works well albeit at a lower flow than a line powered unit. This is understandable due to being battery operated. One problem was that the on/off button is raised. During a recent trip, my suitcase was tightly packed and after closing it, I heard the flosser running! Had to open the suitcase to reposition the flosser. Suggest improving the power switch to prevent accidental turning on.
