I have my UPS mounted under the back of my desk. This mount worked very well. I intentionally left a gap at the top because my UPS has vents at the top. Most computers don't do this, so you can tape them firmly to the top to keep them from moving. I'm a bit concerned about the plastic buckles that the straps go through to fold them over and allow the velcro to hold the desired length. This mount appears to be rated for up to 100 pounds so my 25 pound UPS shouldn't be a problem. However, I would prefer that they use metal. The instructions don't help you choose which set of straps to use (there is one set for larger and one set for smaller devices) so I chose the right ones by trial and error. The instructions also don't specify which direction the straps should face when threaded through the slots (the Velcro side should face away from the device you're hanging). Again, trial and error shows what's right, but that's exactly what the guide aims to do for us. This is an inexpensive mount that does exactly what you need it to do. It can hold things vertically or horizontally. It doesn't rotate or slide. It just keeps things in a fixed position well. If the straps hold up as they should and the instructions improve, it's worth five stars. (By the way, I installed my UPS on the same end of the desk as the computer. The extra weight on one end was unreasonable in hindsight. Now the desk wobbles a bit when it moves. I'll be moving it until the other end some day. Keep that in mind if you decide to do what I did.)
