Pretty good, couple of issues.
Very solid unit, handled power outage well.
few little problems to mention
1) The Cyberpower UPS was set to silent mode. There was power outage, and the unit still beeped at some points. So it is not fully silent, yet there is hardly any mention of it in the manual. If you want to keep it in the bedroom, beware.
2) After battery was exhausted and the unit shut itself. The power returned few hours later and the battery was fully recharged, but the unit had to be powered on by pressing the button. It would not "wake up" all by itself. Not sure if there is a setting to overcome this obvious issue.
