Title: Seems to work fine
Review: Bought 4 of them and one came in faulty and would have needed a warranty repair (just had a flashing blue light), but it was promptly replaced by Amazon via no-cost cross shipping. So far units seem to work fine, computers behave well when units are unplugged from wall, and run time estimates on screen seem reasonable. I downloaded Linux version of interface software from the CyberPower web page.
Is the review positive or negative?
