Effective tool

You get what you pay for. Won't order again.
Color: Birch, Size: 1/2"x 100ft, Color: Birch, Size: 1/2"x 100ft
Inconsistent width, and soft glue. The veneer is so thin you can see the plywood layers under it in places. The 1/2" width varies from 0.55" to 0.45" and was too narrow to cover the edge of my 0.46" plywood in spots. Even when fully cooled (left some pieces overnight before trimming) the glue is soft and tacky, and loads up on the edge banding trimmer blade. I was able to cover all my pieces, so I still gave it 3 stars. But I won't order it again. It's not worth the couple of dollars I saved. I also ordered a roll of 3/4 and threw it away. Same issues, and the color was way too light (looked more like raw maple than birch)

Great spacesaver for desk. Easy on-monitor installation and I couldn’t beat the price.

Nice for cable management
Real metal so it is very sturdy and if you tighten your screw it will be very stable too. I out it next to my monitor mount which provide a nice setup for cable management. It fits perfectly to a VESA 100x100 mount. I have a similar setup in my office but under the desk which makes it versatile.
