Someone mentioned a while back that there are quite different levels of quality with Cat5e cable, and that some are much more susceptible to being damaged, especially by the cable being kinked while running it. Does anyone know more about this, and what to look out for when purchasing? Also, when purchasing crimps, is there a difference in quality with these? I bought a 500m of grey cat5e a couple years ago, and a heap of crimps off ebay. Even when running small cables, I sometimes need a few attempts to get the cable to test okay.. I don't recall having the same issues in the past. Any helpful hints?
