    I got this device to hook up my tower PC. I wanted to prevent unwanted shutdowns due to power outages and it has done just that. It's an affordable solution and I am very pleased with it.

    It works just fine to keep my cable modem & router up and running in the event of a power loss. I like the taller design with the plugs on the top - makes it much easier to plug things in.

    Use this to keep a random power outage from shutting down your computer before you can save progress on what you are working on. This seems unnecessary until you with you had it.

    I purchased two of these to backup my modem and router as well as my security system. They were easy to install and have performed well during a recent power outage.

    I purchased this to smooth out power disruptions after hurricane Florence. Attached the phone cable box, wifi server and alarm system. Worked great! Cable DVR and TV will be next.

    Great price and build quality. Provides all the power and functions I need, just to keep my internet modem, wireless router and Comcast DVR Player working for at least a few hours.

    Got it on sale to replace a really old one that wouldn't hold a charge any more. 10 minutes to unplug the old one and plug in the new one. no complaints or issues after a couple of months.

    Bought this to protect a small freezer that always shuts down during a power cycle during storms. Ever since it was plugged into the freezer, never had a problem again.

    I bought a cheaper battery back up at Walmart thinking it would be fine. After the first power failure it failed me. So I went to Best Buy and got the reliable APC battery back up. Won't buy any other

    Keeps my elderly parents' power lift chairs working during the occasional power failure. Also powers their cordless phone. Does what it is expected to do. Not the most attractive design, but it's hidden on the floor in back of the chairs.

    This is the third APC battery back-up device that we have bought. We use this one to power and protect the router and associated devices. It works exactly as we expected.

    Great product all around, really sturdy and comes charged already, could not have gotten a better deal, I mean I could of gotten it free but I doubt best buy would do that for me.

    Been using APC Products for years, it is my go to brand. I've never had a problem with them in the past. The smaller version is for a temporary power outages only, and will not back up for hours.

    Been running constantly for about four months, have lost power twice and it gave me time to safely shut down - just as advertised. Great value, definitely recommend.

    I assume that this works as it’s supposed to. We haven’t had any outages since purchasing. I like the fact that you can turn off the warning beeps because that drives my poor dog crazy.

    Replaced my older cyber power UPS that completely failed. The battery replacement cost more then just buying a new. I have always had better luck with APC. Worth spending the extra few dollars.

    My old one died and is no longer made. The company recommended another model; but it wasn't available for purchase at Best Buy. This was the closest model.It is working; easy to set up.
