Bests & Worsts Reviews from Amazon

All I wanted was a battery backup for my work's desktop computer so that when the power went out for a few seconds, I wouldn't lose all my work. So I bought this despite the negative reviews because even if all i got was power for 10 seconds, it would make a world of difference for those one second power blips. It arrived yesterday. I plugged in my desktop and two 27" monitors into the battery backup slots and let it charge overnight. So this morning (~18 hours later) I decided to pull the plug and give the system a test. I ran youtube videos in the background and kept opening and closing programs AutoCAD and Revit programs in the background. The computer and both monitors ran for 16 mins and 6 seconds before losing power. That's AMAZING! With the reviews I had read, I thought I'd get 10-60 seconds. But 16 minutes of power backup! I've attached a picture of my computers power specs for comparison. Even if you custom built a computer 5 times the power of mine, you'd still get over 2 minutes and that's on the 600VA.
