    Great little UPS Backup system - we got a few storms lately, and lost power a few times, one of those, damaged my Modem. Lesson learned, got this unit, and protects my equipments - not only that, in the last power outage, it last 4+ hours keeping my modem and wifi router without a problem!

    This was purchased to provide momentary backup for a PC until the generator kicks in. Excellent price for a UPS with this feature set and power rating. Haven't had a real outage yet but the unit and the software provided worked flawlessly during testing (I may not actually use the software but I gave it a try anyway). The construction seems solid and the UPS fits into a relatively small space. The offset plug is a nice feature for cramped installations. If this continues to perform well I plan on purchasing a second unit to back up cable modem and router.

    This unit is easy to set up as it comes with simple, straightforward instructions. Since installing it we’ve experienced 3-4 brownouts and lost power once for about 30 minutes. The unit allowed my computer to stay on for the several seconds needed during the brownouts and the one time the power stayed off for half an hour, I was able to save my work and power down my computer within the first five minutes. The unit works as designed.
