The good and the bad?
Well, the good is that they're awesome. The bad? The finish, on the UC9's slide anyways, is not what I'd consider wonderful.
My UC9 Pro has proven absolutely reliable and is capable of some very tight groups. Of the near 20 autos I have, there are only 2 that I would be shocked if I experienced any form of malfunction. One of those pistols is my Bersa UC9.
I believe they are truly excellent pistols, especially for the price they can usually be found for.
