    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.

    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

    I have not been through a real power outage test yet, but I love the form factor of this UPS. It is light weight (less than 7 pounds), narrow, and has key holes for mounting in vertical and horizontal orientations. That, coupled with an ingenious case notch that allows the power cord to be routed several different ways, makes this the perfect UPS for mounting to a wall or desk, if desired.

    Due to the upright design and 2 USB ports, this UPS is easy to put almost anywhere. The plug spacing allows walk warts to be easily included with other power cords.
