    Works well for a good price. The electric is lousy in this house and Hurricane Ida just passed through without issue.

    My power went out in the middle of using my computer with this. It had enough power for me to save my work and shut it down. Saved my life!

    Works great for my purposes, providing clean power with plenty of outlets. Haven't gotten a chance to test the battery side, but it's been pretty darn impressive so far.

    As stated above, I returned this unit unopened for a larger unit. I gave it an excellent rating based on how the larger one functions. Both are CyberPower units.

    Can't go wrong with CyberPower. Used to use APC, but CyberPower has been far more reliable and long-lasting.
