I am very critical of games and enjoy playing for hours almost every day. Hand fatigue was taking a toll on my hands and wrists and I tried many thumbsticks to alleviate this discomfort and improve my accuracy in FPS games. Not only were these grips inexpensive, but they were also very user-friendly. I actually tried them because they were two different sizes, giving me more options to find the right combination that works best for me. What immediately caught my eye and was paramount from the moment I bought it, was the size and shape of the handles. The large surface area means more range and less force you need to exert on the joysticks to move or aim. This helped get rid of sore fingers and stiff wrists completely. They offer a good grip so your thumbs will never slip off for any reason. This is a must have for any gamer looking to dominate Call of Duty and similar shooters. You won't regret buying them. Two thumbs up for that.
