LIFT THE CORD. RAISE YOUR GAME.

Game smoother with the B4. Xtrfys patented mouse bungee design is made to be both steadier and more flexible all to help gamers improve their play.

FLEXIBLE ARM.

The idea of using a mouse bungee is to make your mouse movements smoother, so why not make them as smooth as possible? Using a flexible silicone arm instead of the conventional metal spring design, the B4 is designed to follow every swipe without resistance and give you an unmatched wireless feel.

STEADY BASE.

While the arm of the bungee needs to be flexible, the base has to be immovable. Anyone who has had a mouse bungee move or fall over in an intense moment of the game knows the importance of having a low centre of gravity. The B4 is engineered to stay put.

QUICK ASSEMBLY.

Detach the silicone arm for extra durability when youre on the go. And set the bungee up quick and easy when its game time. Put the silicone arm in the base, slide the mouse cord into the groove of the arm and the clip at the back. Youre ready in ten seconds. (If youre slow.)

COMPACT DESIGN.

Designed to hit the sweet spot between a small footprint and a stable construction, the B4 is minimalistic on your desk and compact in your bag. Or your pocket.
