I fired two of them and they both worked OK for the relatively few rounds (less than 100 for both) I fired. They bear an outside resemblance to the BHP, but are a totally different gun inside, with a conventional DA/SA lockwork more like the S&W pistols than the BHP.
They are all milled steel, and can stand some smoothing up and burr removal for best feel, but IMHO, they are OK and, I think one would be well worth that price if in good condition.
