With the idea of providing a better gaming experience for the game players, OBKBO controller back button attachment was created. It is absolutely the best answer for advanced game players who pursue the ultimate game play. Ergonomic researches were applied to the design, allowing the back buttons to fit perfectly with the controller while having an elegant appearance. The high-definition OLED screen is amazing for the clear vision it presents. No complicated setup progress, so you know where you are at a glance. Macro-enabled gear is a great way to free your hands, allowing you to handle even more intense combat situations. Three more advanced functions, Mapping, Turbo and Auto Turbo, give you chances to have better game performance. Whether you're playing FPS, RPG, or any other type of games, (example: Splitgate Beta, WWE 2K Battlegrounds, Virtua Fighter 5 Ultimate Showdown, Rocket League, Fortnite, Apex Legends, Rec Room, Rogue Company, God of War, Friday the 13th: The Game, Brawlhalla etc.), you're definitely going to have a different experience than you've ever had. Three sets of memory save you a lot of time, you don't need to setting it every time you start the game.
