Average Reviews:
(More customer reviews)After less than two weeks of operation, the unit began to buzz very annoyingly. (Anyone remember what a 60 cycle hum sounds like? It was like that.) The only way to get the buzzing to stop was to physical unplug it from the wall. I called APC support an was told these units "can have an audible hum" and that any replacement unit would probably give me the same problem.
I returned the unit today, as the noise was driving me crazy. Note: You have to contact a human at [...] to do so as their online return system does not work if you got stuff via Amazon. Let's see if I get the refund.
I'm giving it two stars, rather than just one, because it did at least work with my computer, which is more than I can say for the last one.
