A fusion of German engineering and Swedish design: CHERRY and Xtrfy becomes the new brand CHERRY XTRFY. The mission: to provide professionals, enthusiasts and die-hard gamers with the necessary tools to unleash their individual potential on the way to victory: IN IT TO WIN IT. The idea behind a mouse bungee is to make mouse movements more fluid, so why not as fluid as possible? By using a flexible silicone arm instead of the conventional metal spring design, the B4 follows every movement without resistance and offers you an unparalleled wireless feel. While the arm of the bungee must be flexible, the base must be immobile. Anyone who has ever experienced a mouse bungee moving or falling over in an intense moment of the game knows how important a low center of gravity is. The B4 is engineered to stay in place. Quick to install: Loosen the silicone arm for extra durability when you're on the go. And when it comes to play, the bungee can be quickly and easily reassembled. Insert the silicone arm into the base, slide the mouse cable into the groove of the arm and the clip on the back. In ten seconds you will be done (when you are slow).
