Crimps perfects 100% of the times. Very reliable and durable.
This is one of the best ethernet head I have bought in the past 2 year. These days if you buy dlink, you get clones of it which don't crimp properly or are missing pins. About the product. It was metal shielded, everyone had all pins, felt very high quality. Wires were easy to put in. It's also fits snug in by tp link smart switch. I got full 1000mbps duplex connection with this. Performance I tried iperf 3 with jumbo frames configured (9000 MTU). Got nearly 1GBPS around 980mbps up and down. Small drop in performance is not due to cable but probably the switch getting flooded with frames. Latency also felt on par 0.1 ms. Pull Test. I tried to pull out the head with reasonable amount of force. None of them pulled out with that amount of force. Reasonable force is the force you might exert while accidentally pulling the cable. Overall Good product, go for it. Never expected this brand to be this good.
