    I bought battery back up to keep my security camera and thermostat accessible during a power outage. It works great so far.

    Hooked this one up to large LED flat screen and ancillary equipment. Greater feeling of safety than a power strip. Easy set up. Simple instructions and clear markings on housing. Size is small enough to place it out of sight. Two recent major lightning storms and no issues with any of the equipment connected. Doing the job I wanted it to do.

    This is a great UPS and provides ample time to shut down a computer in a power outage so that all progress can be saved. Also does well against power surges and brownouts. Doesn't take up too much space, and ample spacing between plugs to allow for all kinds of components to be connected as needed. Recommended.

    Just own it for a week, working fine, not sure if the battery died soon or not, but it is a very reasonable price UPS.

    APC has been my go to company for my battery backups for years. This product re-assures me why that it. If you need a battery backup this one would do the trick unless you need a really beefy one.

    If you have computer battery backup is must. You don't want to crash your hard drive when light goes out.

    This is a good basic surge protector with a battery backup. I was able to hook up about 4 items to it. Looks like the battery can be replaced when needed too. Will see how long it lasts

    I find this brand to be the most reliable for me. I only wish someone would come up with the plug holes facing the other way on a couple of them to fit the AC adapters better.
