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).

One minor bug
Size: 10 Ft (Type B with Clamp), Color: Black
I received this today and mounted it to the table I have next to my recliner. I plugged it into a remote control outlet so I can turn everything off at once. I used two of the AC outlets for the power recliner. I then plugged a USB powered fan into one of the USB-A ports. I plugged the power cable from a set of speakers positioned next to the headrest of the recliner into the other USB-A port. I used one of the USB C outlets to charge my tablet. When I hit the switch on the remote control to turn off power to the strip before going to bed I discovered a bug. The only way I can describe it is a cross port power bleed. After killing power to the strip my speakers were still playing, not well as they had static. I discovered by trial and error that if I unplugged my tablet the problem stopped. Apparently if you have something with a battery plugged into one of the USB ports and have something plugged into the other USB ports it pulls power from the device with the battery to try and power the other devices plugged in. Other than this one problem it seems to be just what I was looking for.

Mounts to desktop
Size: 10 Ft (Type B with Clamp), Color: Black
Helps keep the desktop clutter down. Sometimes I need to charge flashlights, earphones, hearing aids, portable battery chargers and the like. I don’t want to plug these onto my computer so this unit fits that need. Sturdy desk mount so one hand plugging in and unplugging usually works fine.
