Customer Reviews of Tripp Lite SMART500RT1U 500VA 300W UPS Smart Rackmount AVR 120V USB DB9 SNMP 1URM
I bought this as an under monitor solution to keep my PC working through bad power. So far it's survived a few brown/blackouts and countless surges and it's still working strong. A lot of features for a 500va UPS and still a good price.
This item arrived DOA (dead on arrival) - completely unable to power up at all. Because we were in the process of putting a server system together, I did not hook this unit up in the first two weeks, and because of that delay, I was unable to return it to Buy.com and will have to work through the manufacturer.
