I'm actually not using mine, they're still sitting unused in the box as I have a separate BT numpad that is it's own thing with it's own style. If you'd like to find a safe way to conduct a transaction, I am willing to part with them. Some extra options for the +, 0, and Enter keys. I'd rather have them go to someone who desires them, than sitting in my closet, forever without a home. :(
That is what I found when looking info about it as well. "DCD is single shot PBT dyesub."
But also: "Both (DCD and DCX) profiles are cylindrical, and both are sculpted. However, the exact contours and sculpting are not the same."
I see them both as Cherry profile, so lets say the only difference is DCD is PBT dyesub and DCX is doubleshot ABS
