It works but doesn't last years for sparing uses
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I used it to back up power for an internet modem and a wireless router. It does its fine. However, after a few years being plugged, it does not maintain an acceptable duration during power outages. It is somewhat disappointing that it doesn't last long before the backup battery needs to be replaced.

Low wattage UPS
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Low wattage, good quality, but not good enough for a desktop backup. It trips the protection with a monitor and a desktop connected. I returned it.

Good basic back up

UPS OK, Software is not very good at all.
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.As a UPS/Battery backup, this unit works fine. HOWEVER, if you want to use it to shut down a PC if power starts to run low, it does NOT work very well. After a power hit, the software gets confused, and at the end of a timed period IT DROPS POWER COMPLETELY WITHOUT WARNING. Their support people think that is a feature, I see it as a MAJOR FLAW. So, if you want to use it without hooking up to a USB port, its fine, otherwise, bewere.
