Review title: 2 out of 3 ain't bad - or is it?
Product review: I bought these units as a 3 pack and I find that 2 of the 3 units still function after less than a year. It would seem to me a unit designed to be a failsafe power failure device should be capable of being plugged in, left alone, and available when needed, which should be infrequently.The unit probably suffers from inferior quality cells and should probably be cycled on and off on a regular basis. They last just long enough to satisfy the warranty period.I noticed other people mentioned when this unit is plugged in to a normal duplex outlet, the other plug becomes unusable which is absolutely true.
