$300 for a video game controller? Must be the helical gears!

I noticed some gear news tucked into a press release for a new Logitech video game steering wheel:

Logitech (SIX: LOGN) (NASDAQ: LOGI) today announced the Logitech® G27 Racing Wheel. Designed to deliver the definitive sim racing experience for the PC and PLAYSTATION®3, the G27 features a powerful, dual-motor force feedback mechanism that smoothly and accurately delivers high-fidelity force effects to the hand-stitched leather wheel, so you can feel traction loss, weight shift, and the surface of the road. The helical gears deliver exceptionally quiet steering action, virtually eliminating noise and unwanted vibration.

It is neat to see the peripherals manufacturer giving some credit to the inner components that make its products actually work well. For the record, helical gears are types of gears whose teeth are not set parallel to the axis; that is, they're set to an angle (which makes them appear in the shape of a helix, from the outside). They run more quietly and smoother than the more common spur gear.
