When they first came out I messed up on the form and accidentally bought two. Best mistake of my life! One I keep twisting around while the other I've displayed in its perfect condition. I am so tempted to sell it yet it's too beautiful. My point is once you find your Golden Cube, you will not want to part with it!
Same thing happened to me!
And I did the same thing, played with one and kept the other one untouched. Managed to sell it recently for $325 too.
