    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.

    I recently bought a new computer and felt that a surge protector and battery back up was an absolute MUST. I purchased this and actually had a smaller power hiccup at my house due to high winds. I felt totally at ease that my new computer had an extra layer of protection.

    Necessary for protection of computer, as frequent power outages in this remote area caused computer to crash. Often. On installation, this protected the computer at least five times so far with an alarm that allows you to hear power out and a battery backup that works, allowing closure of programs and computer shutdown safely. Best functional purchase last year.
