Really? That's what you read in the specs? Here, I thought that good
quality surge protectors would do that, and my UPS does says surge
protection as well as UPS. IIRC, UPSs, and better surge protectors, offer
a multi-thousand dollar warranty if it doesn't stop a large surge and your
system's fried.

which they say is suitable for SOHO usage... and you notice the "connected
equipment guarantee" (CEG): between $25k USDand $100k USD, depending on
model.
