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.

Useful and Stable!
This has earned a permanant spot on my desk or any desk I might get in the future. Very convenient for charging devices, including USB-C outputs that are popping up more and more. Very stable, I never have to adjust it.

Great quality
Easy to use, and design makes it functional to move and adjust as needed. Safe with children and the size is good for where I placed it on a small sliding table. Quality is pretty durable.

Pretty good so far
Color: White, Size: 6FT (2U1C)
Perfect small size for what I was looking for, I wanted one for my standing desk (and in white for a cleaner look) that didn't take up too much space but still offered all the ports I was looking for. The clamp works great, easy to install, I like that on top it has two tiny lights to indicate that it's on and working well. Mainly I really appreciate that it came with one of those white velcro cable wrap so I can properly wrap the excess length :)
