I had used another grip cover and found I had to do all sorts of straps and extra material to make them tight enough. These grip covers are perfect and it has improved my performance due to no more slipping. Love them.

I got the free set after my first week of playing SN for a 5 day stretch. I was so happy after I started to use them because it provides a MUCH better handling of the controller and I don't fear them slipping out of my hands after intense work outs.
