    Needed a battery back up system quickly. Went on line - saw it on Best Buy's site and drove over to get it. In and out in less than 10 minutes. My devices are now protected again!Ea

    We got this after a storm. The power comes and goes because they are fixing the lines. This saved out computer and receiver. Plus our tv sound stuff. It’s amazing to have one less thing to worry about.

    Bought this to keep my router and WiFi up when electricity goes out. It works just as described with no issues. Storm came electricity went out and we still had communications on all of our devices.

    The battery back up caught me off guard when I tried to disconnect computer equipment before a trip. Not sure what would happen to battery if unit left unplugged for any length of time, while it was trying to run my modem. ????

    This Battery Back-Up UPS provided the stable power I needed for my computer. The primary source had fluctuations but the UPS provided consistent stable power for sensitive networked PCs.

    Needed this for security camera system, and it does what its supposed to. The only thing that would be better is if the plugs were turned 90 degrees, so there would be more room for the power adapters.

    This is the second cyberpower UPC I have purchased. I like the way it works and Best Buy had a favorable price. It seems, however, that battery replacement is not a very viable option. It seems wasteful to throw away a whole unit just because the battery wears out.
