    It's a very good product and after many years you have to replace things and you go back and get the same things again.

    Poorly Made

    The interior elements in the receptacle do not line up with the slots in case. It is very difficult to insert a plug. I finally forced them in. These units, I bought 2, have been returned previously, one did not have the manual, in the case of the second one the box interior was damaged. You would think someone would check returned items to see what the problem is, and not just put them back in stock.

    I bought a couple of these and one of them would sound its alarm every so often. Not sure if I got a bad one, but It was already to late to take it back.

    If you need a quality battery backup system, you won't go wrong with APC systems. They are worth the extra money.

    Everyone should have one. If your power goes off this gives you time to shut sessions down properly without losing your work.

    Unit was designed very well. Cord length was longer than expected. Unit has been working for @ 3 weeks now-no problems.
