Extremely easy setup, was immediately recognized by my Unraid linux server. Providing 330 Watts it was high enough to be used for my desktop, server, router, cable modem and switch. 3rd party software for windows allows my desktop to connect to the UPS (which is hooked via USB to my Unraid liux server) to obtain status and notifications via ethernet. Works perfectly

- Works as advertised, supports my mid-range PC with dual monitor setup long enough to save, close my work & shutdown when outages/fluctuations occur - power supplied to my devices plugged in remains consistent & entirely uninterrupted - Has lived through over a dozen power flickers & full on outages in my small town which is notorious for frying household appliances with our terrible power company (in southern Ontario, Canada) - Alarm when wall power is lost and UPS has kicked on can be turned off/on - Alarm, when on, is not excessively loud - the word alarm makes you think it will be screaming at you but it's comparable to a microwave button beep, probably a little bit quieter - When alarm is turned off, it still makes a very audible click when kicking on due to external power being cut off, so unless you have closed headphones or are blasting music you'll probably know the power went out if you didn't have any other indicator (like you had your lights off in your room mid-day or something) and can begin shutting your stuff off

Great product. I forget it's there until the power goes out, and it gives me more than enough time to shut everything off. Been using it for a few years now and the batteries are still good. Better than the AP* brand we use at work.
