I was pretty disappointed with my BoP repro. I came to eventually accept it as just being 'different' rather than a proper reproduction or replacement. The colours are different which isn't an issue (the colours look much better than the original), my biggest problem was the detail that was lost. I've talked about it before, but there are entire sections of her nose that's just gone, as well as many other areas.
CPR are fantastic for doing what they do so I'm not complaining. Just voicing what others have said here that, if I were to consider another CPR back glass, I'd wait to hear feedback from other people before purchasing.
