Sure have, we do alot of sheetmetal fabrication and use dies in are press break. We go to auctions once and a while and bought some press break dies, most of them were all U.S.A. made. Which is what we expected until we got the pallet load home and looked through it. Once we got to the bottom of it we seen some chinese stamped garbage. Also just to let everyone know this pallet was all new dies. The male and female matching dies didn't match up together worth a dam and varied in height from one end to the other. Rough edges and just total garbage, garbage thats exactly what I expected from china. Tried them and they bent horribly off. You want it done right you go U.S.A. There's been other things I've messed around with at friends houses that they bought chinese which were also total crap. Mills, lathes, tooling for mills and lathes, drill press, hand tools, power tools and all were and are total garbage. They ask me how can you afford to always be buying U.S.A.? We buy not only new but used and it always pays off in the short and long term. U.S.A. made tooling and machines do the job and they do the job good. Chinese and other 3rd world foreign tooling and machines are completely inferior to the U.S.A.'s. When I buy U.S.A. I know what to expect, when you buy chinese you don't know what to expect, it's a gamble that your going to lose.
