Yay!  It came.

This is a rather small portable friendly game controller. 

I chose the Gamecube colors because I like Gamecube.  Anyway, like with the SNES 8bitdo controller, the d-pad is unfortunately subpar (I honestly don't get why all of the reviewers phrase the d-pad so much)

Here is some image comparisons of te two along with a Logitech controller (about the same size as a playstation 3 controller).

Something to keep in mind.  While the "Gamecube" controller doesn't have that much smaller of a footprint then the SNES one, it's quite a bit thinner, thus it will fit in most pants pockets. 

So if you're looking for a very portable bluetooth controller that has all of the functionality of a full size controller (albeit with quite a few ergonomic sacrifices, the analogue sticks have a very short through, so they are quite sensitive, and the L2 and R2 buttons are side by side instead of top and bottom like most controllers) then this may be worth looking into.
