Negative Positive
Title: bzzzzz
Review: This UPS has an internal 24 volt fan (with no fresh air intake or exhaust!) that makes the whole case buzz. Mine looks nice but when the power goes out it just lights up overload (on what it says is a 216 watt load in the Windows application) and the computer instantly turns off. Too bad I voided the warranty on mine trying to replace the fan with something more quiet. I used to be a big APC fan but this is a poorly designed product.
Is the review positive or negative?
