This is a well made dongle. But be careful! it will not work on an old Dante wall plate. I've been looking for a key for my old Dante valve and wall plate and even called Dante to find out why the tip of the key wouldn't fit the hole in the old wall plate to no avail. What I had to do to use this key was file the round end of the key with a metal file and now it fits the old wall plate and works great.
