Trusted by numerous professional gamers, KontrolFreek Ultra was developed for the sole purpose of enhancing your gameplay experience by increasing player accuracy and control. Proven a winner time and again, Ultra has been our most popular Performance Thumbstick year in and year out. KontrolFreek Ultra’s 10.0mm of added height increases the analog stick radial distance by 47%, which provides a range of motion increase of 135.5%. This gives you the ability to make smaller, more precise in-game movements, affording you the luxury of turning up controller sensitivities to maximum levels so you can turn on your opponents faster and gain the upper-hand. KontrolFreek Ultra also gives you better control while requiring less force-alleviating thumb-fatigue-and adding more comfort to long gaming sessions.
