NES Pro Bluetooth Controller

I attempted to post an image but my work computer is being annoying. Either way I'm seriously looking into this, I like the look of this, and if it can do what it promises, this is going to be a fun little addition to my gaming on the road when I am away from home. Plus it's fun to think about playing on the old school controller that's been updated.
