Title: Unreliable in the Long Run
Review: I have had two of these units. Both seemed very good at first. With the first one the battery failed after a few years of operation. I found it is not feasible to replace the battery, but at least the software told me what the problem was. The second one has now become nothing more than a very bulky surge protector. When the power fails it just cuts off suddenly. What`s worse, the software gives no indication that anything is wrong. I intend to junk this unit and buy a different, more expensive brand, in hopes of more reliability.
