The patterns you are referring to are on the bottom of the joystick base. When you project these patterns up towards the top of the controller in a 3D cad model, they get exaggerated into the corners on our device if you want to maintain the same movements. While it looks like the joystick handle would be limited to a cross shaped pattern, with the spacing and tolerances, it actually translates into a diamand pattern (Will take and post a video). So basically, the movement of the joystick is exactly (or as close to as possible) the same as a happ 4-way stick. Our product comes with a satisfaction guarantee.
PaigeOliver, I'm not sure what your area of expertise is, but based on your rather immature response...it clearly is not engineering or running a business.
