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.

Does the job
Size: 10 Ft (Type B with Clamp), Color: White
I think the clamp could be some show shorter, but the product looks nice and minimalistic and works perfectly.

Solved Specific Need
Size: 10 Ft (Type B with Clamp), Color: White
Nice product which solved a problem of needing USB power clamped to a very thick work table. Most power strips with a clamp do not accommodate thick tables between 1.75" and 2" so I was happy to find this one. Successfully provides power to all my USB devices even a laptop (although charging is a bit slower compared to the OEM power adapter).
