    Compact but seems sturdy enough The cable was long enough to go through my entertainment center and still reach the outlet.

    I was tired of the brownouts in my area where just 3 seconds of power loss would force the rebooting of my base station...this solved the issue..instantly..

    I was looking to replace an old UPS. The previous one had lasted a decade - and I went with the same brand, seeing the quality I have come to expect.

    Perfect option for modem backup when the power goes out. Gives you enough time to shut down your work before you lose it.

    Big and bulky but does its job! It beeps when power goes out, keeping what you have plugged in on till you can safetly turn it off.
