    Well, I bought two of these, patting myself on the back for saving $$ over buying APC, but......the main goal of these was to MAINTAIN power to my computer and internet gear in the event of an outage (one feeds Spectrum modem and router, the other one is on my PC/Monitor). We've had a couple power outages as well as a couple power "hiccups", and in ALL cases, the computer and internet gear dropped immediately. Sure, there was still power in the batteries to boot them back up even without house power, but the WHOLE POINT is to KEEP them running without dropping, which these are not fast enough to handle, thus they are completely useless. OH, and I also had a third one, which was the first purchase, and the battery hit end of life not long after warranty expired, but never got the chance to "catch" it doing the same as above, or I would never have bought two more of these paperweights.

    No, I would not recommend this to a friend

    The 4th one I have. They last - not as long you are expecting, but do the job at protecting your connected equipment from surges.
