Electromagnetic grips that I will install on it, they will arrive in a week. Their name is Gulikit 720, the best modern grips agreed upon by professionals. And it breaks the hand's speed to 1000hz, guaranteed by Sony. And the third thing, it comes with a box for the grips that will arrive in a week. You can lighten them, make them heavier, and increase the grip length in a way that suits you. There is a picture of the product. The sale is to the highest bidder. For sale, DM me.
