I didn't expect the internal wires to be so thin. They make it very difficult to add ends (both regular ethernet ends and keystones). They came out of the keystones very easily after they were inserted (they would often break off when being crimped in). When putting into regular ends, the wires are so thin, they would go in between and not be in line with the contacts. Quite disappointed in this cable and won't make the same mistake of going with a very thin gauge wire again.
