It's been a while since I've seen this thread... apparently it's become popular again!! Update on my Zev connectors, I've had some that work, and some that will not work at all in both a gen 3 and 4. I don't know if they had a bad batch or what, but some just didn't work! I've gone to all TTI connectors, and all has been well with those! When I didn't overpolish and left things stock, they were a lot more crisp and the break was clean. Slight change from the original post, but still similar!
