Erson vs. Comp Cams

I don't want to trash talk but Comp has lost me as customer since even their custom products are so out of tolerance. In a current build im on cam number 2 from them and even after catching them on first cam they still send me a cam that's not what I ordered. Closer than first cam but still off and not what I ordered. This is three cams within the last year. Three strikes you're out.
