update from me.
i have found the quality of the acrylic used in my C3s wear out pretty easily. i've had them for coming to 3 years?
the socket just ripped a new hole out of the left side, pulling off the faceplate in the process. looking in it i realized that the acrylic has gone brittle, and its extremely thin all around compared to the moulds produced by Unique Melody (about twice the thickness in comparison).
I'm not sure whether the acrylic quality has changed now that they're working with fisher, but good luck fellas. hear from you in a couple years. it sure seems like Alien Ears is trying to clean up their act, but if the acrylic is this fragile, you can bet i won't come knocking.
C3s have since been sent to UM for a remold. should have bloody done this a long time ago.
