This is junk, when crimped the plastic retainer that inserts into the cable breaks off and just falls out - standard CAT6 UTP is used. This is the case when using EZ-RJ pro, Radioshack and other universal crimping tools. I would like to know how they rate CAT6 if they cannot support the cable at all. They seem to work fine with CAT5 and 5E. Much luck!
