I have it aswell, the biggest gripe I have is that the mini joystick is on the stick, not on the throttle. Together with the sloppy center this makes using mavs real hard without a bit of of deadzone. Other than that its a pretty decent stick AND you get rudder pedals :)
edit: I recently fixed R1 and R2 spiking relatively easily. Downside is you'll have to open the throttle up.
