I have one that I got a while back. They look ok, and overall are decent at that price. The only problem I have is opening the case. Basically, once they snap shut, they are a pain to get open again, so make sure you have the jersey how you want it prior to closing the case.
Also, when I got mine he didn't include the hanger for the jersey. I ended up paying an extra $15-20 for that, and waiting an extra couple of weeks to put up my jersey. He didn't indicate I would need one when I bought. So if you are buying one, ask about the hanger before you pay, so he can include one when he ships
