The Cirka Premium GameCube Controller For Netplay?

[Railz]

I saw this at work today and i know nothing about it. its the Cirka Premium GameCube-Style USB Controller for PC/Mac (Black). Has anyone seen/used this? How is it for input lag? Can it be used for Smash 4? How does it feel in a tournament setting compared to the Nintendo brand controller? I just would like to know before i buy if ill get the use that i want from it.
I saw no reviews that are useful to me. Thanks!

It wont be usable on the wiiu.
Which answers your tournament question.

It will have more input lag compared to a gcn pad with the official adapter in direct connect mode.
