I have a feeling that the Leopold would feel very similar to my Duckys.
In fact, I have a very suspicious feeling that somewhere down the OEM channel, they might be made in the same place (or certain parts, anyway). Either that, or one did a great job in copying the other.
-The cable channels, mini USB port connector spacing are both very similar
-Cherry-style stablizers (not a huge deal here)
-The ABS Ducky caps look very similar in apperance, specifically the windowed caps.
The spacebar mounting point on the Leopold would suggest they may have different OEMs, though.
Time to pop them open!
