Mine does make a slight click but I can feel it more than I can hear it if you know what I mean.Theres no click on the fe either but you should able to do a visual inspection
I registered my interest with Cablemod but I haven`t had anything back yet, there were four versions depending in the direction and 90 degree or 180 degree and also the the thickness of the card so I suppose they`re gauging interest to see if it`s viable or not.Any right-angled adapters available yet, out of interest?
