    The only thing I don't like is the spacing for each plug is the same so in my case some power cables take up 2 spaces.

    So far the device is working well. It replaces a similar device by the same manufacturer that lasted 5 years and then failed. Hope this does better.

    I bought this to backup my Network center. I have the cable modem, 24 port Gig switch, Netgear Nighthawk, and a Smartthings hub. All running in the hall closet, This keeps them all running even in a Florida thunder storm with flickering lights.
