Or even sooner than that.  By dumb luck, I bought a couple of CyberPower 
units that do NOT have this serious design defect, AND which are also RF 
quiet. The model I bought is the CP1500PFCLCD. It has RFI filtering and 
meets FCC Part 15 Class B.

I'm guessing that I bought the first of these units 4-5 years ago, and 
it's been protecting a big "old iron" Dell tower ever since. Run time 
still seems quite good. I bought the second one a few years ago to keep 
low power 120V shack gear running through the occasional power drops we 
experience up here in the mountains. Both units are plugged into a 
SurgeX box.
