Works great for my desk
I like being able to plug things in above and below the desk. Plug in the things below that I want always plugged in and can easily remove the ones on top

Good device! I was able to mount it between 2 desks that are head to head, and we’re able to share the plugs very well. Plenty of space to mount on my 2” thick desk.

Great value and capacity for the real estate ratio is perfect.
It certainly takes up less real estate on my desk with a very high port capacity. It's solid and I like the fact that it can attached to a thicker surface. It was very easy to install and the plugs give good options as there's always some cord that can't be plugged in. The USBs are a bonus as I already have ports on a different device. But, I'm sure I'll end up using these USB ports eventually. The value is really good for the capacity you get. Having the strip further in to use the back plugs easier makes a lot of sense. Could be an issue for some who don't have table real estate as it does push the strip in a bit.
