Input:
I just finished crimping my 10th RJ45 connector and my success rate with this tool is 100%. I can't imagine why anyone would purchase a more expensive tool, since this one works absolutely perfectly. Unlike the report from another reviewer, I found the length of the wire left by the stripper to be just right. However, you do have to be very careful with the stripper because it's easy to cut through the outer insulation into the inner insulation exposing bare wire. The crimper appears to be very well made and there is no indication that it will stop working any time soon.
