    Haven't really had an opportunity to see how long the battery back up will last. We have had a problem with solid state hard drives crashing and hope that this will solve that issue. Will review later if this doesn't resolve the problems we have been having.

    Bought this to keep the DVR from losing its programing every time the power went out. Replaced the same model with this new purchase. Old one lasted about 3 years. Replacement batter cost almost as much as the whole thing and had to be ordered so it is easier just to buy a new one.

    Survived my first power outage 5 days after I got it -- both computers and modems stayed up and running until the whole-house generator kicked in!

    It seems to be a very nice battery back-up, replacing an older model of the same brand which did its job for many many years.

    Printer/s and phone sets and anything else that work with your computer need surge and power back up for when things go wrong. Well worth the price the first time it does it"s job.

    This is a quality product that has served me well ever since I bought it. The sockets are spaced out well to allow for multiple plugs.

    works great, using this to cover the gap between power failure and when the whole house generator comes on. Power backup is for networking equipment.
