Gravis Game Controllers
Now made by Kensington since the purchase of Gravis in 1997, Gravis has made some decent game controllers, with the most popular being their Gravis gamepads.
Gravis joysticks are a really popular game controller too, many with dual analog controls and their force feedback, Rumble, with two controls that let you turn to each side as you run or accelerate while steering and feeling the hits and explosions in your hands.
Features that have made Gravis popular include easy-reach dual axis giving you exacting control of games with an advantageous gaming D-pad. The controls are positioned well making it easy to adapt to any inherent game controls requirements.
