Review on Enhanced SGILE Network Tool Kit for Cat5/5e, in Sleek Black by John Finley

I've used the crimping tool, punch, stripper and tester and they all worked fine. However, after a few months and about 100 crimped connectors, the tester showed errors on newly crimped cables (interruptions on several pins). A connector easily slipped off the cable even after the crimping tool handles were fully closed to crimp the connector. I noticed that the crimping tool started to bend/deform like a fishtail when crimping --- you can see in the pictures that the head of the tool is no longer in the same plane with the handles. I'm currently looking for a replacement crimper but will be keeping the rest of the set because they still work, at least for now.
