Initially, I was hesitant to try these products; however, after making a pair myself, I wanted to experience their claims of enhanced aim through increased sensitivity and broader range of motion. Feel free to share your thoughts on this item! Upon further research, I discovered a PS3 version by luwe, though I haven't tested it as I don't own a PS3. For those interested in that console option, here's the link: http://www.thingiverse.com/thing:22669. Enjoy your exploration!
