    I always use APC at work and at home. I have several of these units and haven't had any problems with them. Would highly recommend them for any electronics that need protection.

    So glad I bought this battery charger because it has already saved my work. Before I even realized the interruption in my electricity supply, it had begun to beep to warn me that it was doing its job. This product is for you if you're like me--not so tech savy.

    If you have a modem, a router, a computer, and a monitor that you dont want damaged do to power surges or power outages then you need to own one of these. In fact power surges and power outages are one of the biggest causes of tech getting damaged over time (ie: router failure).

    This is very good outlet, it has actually saved me a few times during this nasty Houston weather when rendering videos. The only problem I have is the Ethernet outlet is only 100 mbps and not 1 Gbps . Other than that, for the price I got it for it was wo rth

    I have relied on the APC backups for years. I live in an area with severe weather and power outages. This has saved my computerized equipment on multiple occasions. We run 6 of these in our home to protect video and computer systems. A must have!!

    We have had too many power outages this summer and needed to protect my computer. It was easy to set up and now I have peace of mind when the next outage comes! I also like that I don't have to buy another one, all I need to buy is a new battery when it wears out.
