    Based on use for the past 30 days the unit performs as it should. This product is an alternative to other brands of computer UPS systems.

    Originally bought to replace a Cyberpower 1200 vac but since already had the 750 vac unit decided to use this for fiber modem, WIFI, antenna booster and other peripheral items. I moved the 750 vac to replace the older 1200 vac unit. Will be interesting to see how long the battery last before a replacement is needed.

    We are using this UPS in an environment where the power is not what you would call 'clean'. There are dips and short outages but so far (a couple months) it has worked well and we have not had any issues with the computer rebooting due to power problems. The computer does not draw a lot of power, SSD storage and the screen goes to sleep whenever it has not been used for a while.
