APC Back-Ups ES 350 (BE350R-CN) UPS System

Pros: Absolutely none. A total waste of time and materials. And my money.
Cons: Fails to keep computer running when the power flashes.

I had this unit for approximately 15 months before my first power failure, thus it was FAR out of warranty by the time I discovered it didn't do SQUAT. I've encountered two surges/outages in the past 2 months, and both times it has totally failed to do anything but beep at me. My computer dies even when the power doesn't go out, and it's the only thing I have tied to the battery backup. I am completely and utterly disgusted at the waste of money... I'd have been as well off if I had set fire to my cash. Thank God it's discontinued... if you find one on ebay, run away! I'll never buy anything from APC again.
