ÂThe analog sticks have to be short in order to make Âthem Âcomfortable Âfor children, however, Âadults might not be satisfied when playing some hardcore games, Âwhat with the Âshort analog sticks causing Âover-steering and poor aiming? That's why we designed these two kinds of thumb grips. Note: When you find Âthumb grips Âbecome greasy, Âplease Âremove Âthem Âand clean Âthem Âwith detergent.
