Summary: With frequent thunderstorms, we lose power a few times a year in summer. I have my router and modem VOIP phone hooked up tp the UPS so if we lose power, I will have abount an hour or more of internet.
Excerpt: APC makes the best back-up batteries as far as I'm concerned. I only had it for several days when our power went off. I was able to continue using my desktop, monitor and wireless modem until I could save my data. It truly works when you really need it to work.
Pros: Compact Size, Dependable, Durable Construction, Good Warranty, Great Protection
Summary: I wish someone had told me whether it had keyhole slots for vertically mounting it before I ordered, but fortunately it does. I am using these on the data/telecom service entry boards at businesses to hold power for switches and modems or routers. Works great for this and looks nice.
Summary: I truly protects my computer incase of a power serge with the battery backup. The only dilemma I had concerned the proper hookup of the battery--did I do it right? There is no way I could tell for sure.
Excerpt: Have one 550 on the router and the other on the entertainment center. Works great, like the 2 APC 1500's on the computers. We've had a lot of thunderstorms recently and they all worked as you would expect. At one point we did have a surge that brightened the lights just before power was lost.
