I ordered these about 10 months ago and just started using them and have had all sorts of problems. It turned out that the through holes were too big for the Category 6 cable I had and the pins didn't fit into the core of the cable causing the connection to fail. I contacted the seller to see if they could help and they exceeded my expectations! The seller refunded my purchase even though it was almost a year old and sent me a new pack of connectors with smaller holes (the same as the ones in my crimping tool) so they should work perfectly. I will definitely order from Everest Media Solutions again! I've attached a picture with different sized holes. The left one is a replacement and the right one is the one I ordered. Thanks for the great customer service!
