    I've purchased two of these for my home, and they've never let me down. They're light, they're small enough to fit most places a larger unit would find cramped, and the alert tone when you've lost power is loud enough to wake you up even, so you can unplug things in time. Definitely recommend this manufacturer and this unit.

    so far the UPS works great, it has enough power to operate my 700 watt computer and monitor and modem and Wi-Fi for 11 minutes with warnings that its on battery. shutting down computer and monitor gives me 8 hours of Wi-Fi and modem power to use on other devices during power outage.

    this is a very dependable ups for the cost, which is less than the other big 2.I am using it for my weather station and APRS computer for backup plus surge protection. The battery compartment has a quirky torque screw securing it if you need to replace the battery, which is small, but other than that works for me just fine

    Has 4 surge outlets and 4 surge+battery. May not use surge+battery unless you are powering a battery backup item such as a laptop. So I can only use one surge+battery outlet. However I need more than 4 surge outlets so I use a power strip off one of the surge outlets. Otherwise it seems to do what it should. Make sure it meets your needs.

    I needed to buy a new surge protector for my entertainment center and found this for cheaper than some of the surge protectors. It works great with my modem, router, Xbox One, and surround sound but gets overloaded when I add the TV so it went on a cheaper, lower-rated surge protector. Not going to watch it if the power is out anyway.

    I owned two of these units, both on iMacs. They work great. I purchased a third for my old Mac Pro - the kind with the 30 inch cinema display and upon plugging the computer and monitor into the unit, I immediately got a audible signal. Switching the monitor to a surge only plug, the same thing happened Obviously, the Mac Pro draws too much power for this unit. I recommend this unit for low power uses but not for high demand applications.
