Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    Purchased as essential office equipment. With the recent storms that we have encountered these have been handy to have. Some of the storms came in without warning.

    Definitely useful surge protector...would have appreciate a bit more space between plug outlets as most plugs aren't standard size. Enough to take care of most home equipment and tvs.

    I wanted a battery back up in case of an outage and this one was well priced and seems to work well, although I haven't seen if it actually keeps my PC running during a storm.

    Small back-up that works as intended; gives you the required amount of time to gracefully shut down whatever is connected to it.

    So Good, I Bought It Twice

    I bought this to protect my tv and entertainment system (game consoles, sat receivers, sound system, etc). Mainly, I got it so I could safely shut down everything when we lost power. I knew the battery wouldn't keep it running long enough to outlast a blackout from a storm, but electronics really hate to be unceremoniously unplugged while running. I found this model with a price tag between the cheap ones and the more expensive that would be overkill for me. I bought the first one years ago and it saw me through brown outs and even a few storms that took us down for hours. I have a good 10 minutes to see if it's going to come back on and if not, power everything down in preparation. The batteries finally died in the old one and I discovered the one flaw for my use. When the batteries die, so do the outlets that are battery backed up. So I can't use it as a power strip on those outlets, but the surge suppressed ones still work. I would rather the batteries die and it goes into a permanent bypass mode that just gives me all the outlets with surge protection. But, considering I got 6+ years out of the original, I thought it was a great investment and replaced it with the updated model.
