Review on Efficiently Connect Networks with 50pcs Cat5 RJ45 Keystone Jack Cat5e Punch-Down Network Blue by Delbert Potter

Bought 50 pieces and only had problems. My puncher refused to cut the wire when struck down. I had to use dams to cut loose wires. Not professional at all. Punchdown works with all other jacks I use. Of the 20 sockets installed, 6 failed. Check the downstroke twice and check again. Failed. Re-terminated to the same sockets, failed. Replaced with another jack and it has worked perfectly. Poor quality control on their part. I wonder if I'll get a trouble call in the future.
