    Purchased to protect modem and router to prevent restarts with short power outages. Will see how long it works.

    Need to keep the routers up during power blinks and summer storms this is what you need. Works great for the router, modem, security system etc. mounts to the wall easily or on the under side of a shelf or just sitting on the shelf behind all the gear. Keeps everything running through uncertainty.

    So far I have no complaints about this little backup. I purchased it solely to protect our modem, TV, and satellite receiver and it's done excellent so far. I know we've had at least 4 complete and 1 partial power failures since I hooked it up and we've yet to have any issues due to them.

    I had a power outage yesterday, and my PC was in sleep mode. The device was beeping, so I went to login to my computer and immediately lost power. So, that means the battery was not powerful enough for me to start up my machine and shut down gracefully. I might have too much plugged into it, but I want everything running through this device. It seems like I should have bought the bigger unit.
