Review on Alvin's Cables - 12G HD SDI BNC Cable Right Angle Convert Connectors - Complete Set by Kantrel Tunstill

Edit updated to 3 stars: Alvin reached out to fix this (good with them I appreciate the customer support) they agreed to send me a replacement kit after they informed me that they had solved the problem. In the end they sent two sets as replacement for use. Only one kit they sent really works and doesn't slip right away, the second kit has the same problem as the first. I believe this problem is quite simple and could be mitigated by having a crew member go through the remaining stock and pull out any defective parts instead of going back and forth. First Review: Too bad I didn't pay attention to the other video review post. These are really useless. They fit snugly on the BNC cable but not snugly on the SDI connector. They are loose and you lose your SDI connection if you trust them. Had high hopes for Alvin but it's really bad.
