Does this board look okay to buy?

My friends want to leave a board at my place for whenever they visit. We found a cheap epoxy board for $150.
Owner of the board said it's just a chinese board with no brand. Friend is a little concern that it doesn't seem to have any concave or anything. I want to check out with you guys before I drive out and pickup this board. Does it really look that bad?
