    Works fine so far, it’s used only for my cable-modem router. Hopefully it will run this for two hours in case of a power outage

    Works great. The battery back up is what sold me. Even if the power goes out half the strip will still retain power for 100+ minutes.

    Has already seen several power glitches, long enough to mess up the digital clocks, and it kept the computer from turning off. I like the feature of charging the battery when plugged in but not turned on.

    Lots of plug-ins and great for a home office. Allows for us to plug in more than enough of our office gadgets and provides a nice comfort of knowing they'll still receive power if the power goes out. That being said...within the first week of having it, the power never went out at our house but this unit shut off along with everything else we had plugged into it and the battery backup never kicked in so everything just powered off. Luckily we weren't in the middle of working on anything significant at the time because we would've lost our work. Hoping that was just a little glitch out the box that won't happen again but as far as providing power it's done it's job. Time will tell when the power goes out next if this will do what it's designed to do.

    It hasn't been tested by an actual surge and may never, but as expensive as the TV is, it's a no-brainer to spend a few bucks to protect it and the peripherals associated with it.

    The power in the room where my router sits keeps getting tripped when people use the treadmill. Now they can do their exercise without my internet being lost. Haven't had a problem with it since i installed it.

    I plugged in one end of this into the wall and then used the other ports on the device to plug in other things. That worked as intended. Make sure you plug in for 24 hours before use so the battery charges.
