I traded my ID 2000cc injectors for brand new in box Gram 1000cc injectors. I shipped the 2000's right to him, and when he got the tracking number, he shipped me the new 1000's. Flawless transaction. Really good communication. Never a lag or no reply. The whole thing took less tahn a week. Always replied and kept his word. I see he has had some pretty terrible reviews. That's too bad. This one went just fine.
