Pros: Cheap. The CF slot works.

Cons: The plastic case prevents one from inserting a CF card into its slot. In order to fix this, I unscrewed the plastic case, took out the board, and then inserted my CF card into the slot on the board. I then carefully put the plastic case back into place so that it was lightly touching my CF card. This left a bit of a gap, so I can now plug in my CF card without having to take the board out of its case, but now the plastic case doesn't enclose the board as tightly as it originally did.

Overall Review: I haven't tried any of the slots besides the CF one. You have to plug in your CF card upside down. This makes sense, because the CF card reader is just a standard reader attached to the bottom of the board, rather than the top.
