    Mine didn't last long, about a year. Don't know if it's this particular unit but the other ones that I bought last a lot longer. I still have a couple that are still working fine after 3 years. All of them are from Cyberpower.

    We have a lot of power outages where we live and this provides enough power to keep our computer and electronics going for over an hour. There are more expensive versions that have more bells and whistles but this is adequate for most needs.

    Purchased to use with my small CNC machine. The machine is off most of the time and the battery back up has an annoying buzz, even when the machine is off. I have 3 other back up devices and none of them make any noise.

    I am using this to protect my 3D printer. Within 2 days of installing this, I had a power loss that while only lasted a few minutes, would have caused my print to fail. With this attached, the power outage did not interrupt my print. Well worth it!
