Title: quality control is very poor...1 of 3 worked
Review: I bought this product, charged it up overnight and found it would not work after a single 3 second burst. I returned it, and bought two more, to be sure I could edge before company coming. After charging both overnight, one worked, but the other one stopped after 3 minutes and would not charge again. The THIRD appliance works fine and holds a charge. This is too much trouble to buy 3 to get only 1 that works.
