    The back-up system hasn't really been tested yet but it seems to be working just fine for the couple of brief outages we've had.

    Just what I needed for my internet back up power supply. Hopefully I won't need it, but I feel better knowing it is in place. A good price as well, I think.

    works well. does the job. Just relise the batteries are small and it won't last long even with something tiny like a router. Other thing that really is a deal killer for me. Once power goes out and batteries depleted, you have to physically go to the device to turn it back on once power goes back on.

    I had a power outage and this device gave me time to power down my devices and save my progress. When the power came back all my devices were safe. Worth the price just for that.

    I feel that all my important devices are now protected I have a whole home generator but there is a lag of about 10 seconds before the generator goes on line. I purchased this so I don't have to reset anything and if I am doing some important on my laptop I don't loose the internet.
