My R10 works perfectly now with ver. 4.30. I finally played a tournament round without any 2nd,3rd,4th, 5th....chip/pitch shots not registering. This was the only nuisance I found after having owned for over a year. My shot shape, distance and scores are the same on the simulator as on the course. I'm a scratch golfer and I see a lot of negative comments on the device, seems strange.
