I bought a gray one too, so everything I had to say about that goes for this as well (below). Just add on awesome colors to this. The colors and hues fit in great with the clear everything motif that was so popular in the mid to late 90's.
It's everything I ever wanted in an N64 controller. The analog stick is smooth and accurate. The button placements are all comfortable, and they have great response. I had been eyeballing these for over a year now, and I'm happy to say they live up to all the expectations I had built up in my mind.
