I've seen a lot of harsh feedback for the guy so I thought I'd share my experiences with him. I have bought various high end internal parts from him. His prices were reasonable and his shipping was fast. He communicated well and all of his products arrived as described. I have bought a DSG, RiotSC spacer, RiotSC sp110, AWS Pulse, and various other things from him with a 100% success rate. I had him install a pinion gear for me on a motor and performed the task very quickly and it is still solid to this day after maybe 50k rounds on it. Maybe I just got lucky, but I would recommend business with him based on my experiences.
