Piece of mind

Bought one of these for my Synology NAS so that it handles the odd brown-out and safely shuts down during a power outage. The NAS automatically detects the UPS via the supplied USB cable, barely any configuration needed. When power gets low the NAS shuts down and automatically fires back up when power is restored.

Good display, size, noise - but few plugs and fixed cable

I use this to run a Unifi Switch-8 150W (connected to two downstream PoE access points), a Qotom mini-pc (J1900) running pfsense, and a QNAP TS-453U NAS. It works well, and gets me through power cuts here. It's quite compact and fits nicely onto a shelf on my rack, and has a good, bright, clear display so I can see what's going on.

Works on Linux

Works as advertised. Despite what is stated in another review, this UPS works flawlessly in linux, just not with the companies official software (at least not on my system). You must use NUT. Monitoring and shutdown functions fine. https://blog.warbel.net/index.php/2017/09/15/configuring-powershield-ups-on-linux-and-integrating-into-zabbix/

It may be a great machine, however, I noticed that the support for Linux systems is poor. The Linux driver software is not up to date, and wreaks havoc with Firefox. It also did not detect the UPS. On Windows7 , the UPS works fine. However, the UPS software has limited functionality and comes with large and clunky user interfaces.
