Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    This unit is a great alternative to APC 650VA for about the same price. Easy to set up and is very slim compared to the "flat" models. Easy to wedge into a corner

    The unit worked flawlessly on the first power outage. I am getting one from my Mom also since it keeps WiFi and TV running in event of emergency loss of power.

    I've picked up two of these so far, one for my work system and one specifically for home networking equipment. They're solid little backup batteries (assuming you aren't trying to run some monster gaming or rendering desktop from them.) They don't come charged, of course, so pick them up ahead of time. The software is pretty straightforward, easy to understand with a little customizability. No complaints. It's not exciting equipment - unless you don't have it.
