Look I think everyone here ( nearly everyone) would agree that the quality of their repro stuff is second to none and I and others are grateful that CPR do exist to supply us with new goodies for our favourite games BUT!!!
Yes sometimes they do forget to send stuff and sometimes the response to emails is a bit tardy, but I dont think they have a whole lot of staff to be able to keep on top of this and I'm assuming when they release a new playfield of backglass and they're shipping stuff out they probably have hundreds of orders that all have to get done at the one time.
On 2 occasions they have left stuff out of my orders but it normally gets fixed up pretty quickly.
Overall I'm pretty happy with their service.
