Once wired and installed, it works like a charm as to be expected from Neutrik.
tl:dr
See that you have the right screws, about three times as much time for the soldering and shrink tubes to prevent accidental crosstalk.
Mounting:
Unfortunately they decided use a different mounting style (sliding in from the back) and a different screw socket with that all the non-combo sockets. So keep in mind that you'll need specific screws for this socket.
Wiring:
I guess if you're buying sockets, neutrik expects you to want to do the entire wiring yourself, and maybe there is a usecase where you'd want to wire the jack and xlr connectors ton different devices. I, however, would appreciate a combojack where the jack and xlr connectors are combined out of the box, as doing that yourself is tedious and increases the risk of faulty connections.
