Good mat, feels pretty solid, but the alligator clip came broken. I had an extra alligator clip, so I was able to fix it, but for 20 bucks I expected better. The storage compartments for small screws are a nice touch however I wish the workspace was a bit bigger. My ATX motherboard was hanging off the edges, and was wobbly because it had to lay on top of the screw storage compartments. It should be be fine for smaller form factors. I do some soldering from time to time, so I'll keep it for my smaller projects. Overall, it's a good mat.
