Has anyone used Metz RJ-45 connectors for Cat6 termination?

I'm referring to these: http://www.metz-connect.com/us/rj45-connector-for-direct-attach-application

I'm particularly interesting in knowing if they're worth the premium for when you have to do two or three Cat6 terminations in the field, not for bench work.
