    This is a great battery back up, it is a midgrade one. So not the biggest or longest lasting, or the smallest. I think it is a great middle ground one. Great buy.

    We have used CyberPower products before, however this one was tested on the second day after plugging it in, and held power for 20 minutes.

    Installed about a month ago. We’ve had several thunderstorms since and have not been struck by lightning (yet). As simple to install as just plugging it in, then untangling all the other cords and plugging them in to the unit. And it appears to be working. Who knows, sometimes I think it’s just another ploy to get us consumers to spend. If anything changes I will update this review,—- or not, —-ya never know.

    The item just went out on me a week or so ago and I did not have the box, much less the receipt. So I expected a bit of difficulty with getting it replaced just for those reasons. However, Sean, my BestBuy go-to guy, completely had me taken care of in a flash. Completely A+ Service...really from the whole team.

    Needed to replace one that didn't quite have enough power. This fit the bill. Inexpensive and just enough outlets.

    It's pretty cut and dry. It works like a champ. I would prefer more battery-powered sockets and less surge-only ones, but it works as advertised.
