I just got them in the mail about a week ago, they help with your sensitivity I play on ten so they made it even easier to play on, but it wasn't a huge difference. I personally only use the right fps tho. I like the feel of fps sticks better than ps3 and 360 sticks. They r only $10 plus if you get a promo code they go down to $8 and promo codes are super easy to get. So why wouldn't you get them.
