This was perfect for my project
This fit into my external Antenna control box perfectly. I am using it to ground my antenna connections to a ground rod. Easy to work with and perfect size.

It's a piece of copper
What else is there to say? Edges are decent, finish is very smooth, but if you're buying this I'm assuming you're probably going to cut it up or machine it anyway.

Used for welding
Used this as a backing plate for mig welding along with some strong magnets. Better quality and thicker than others like the eastwood one that falls off all the time.
