I'm a very late adopter of Game Golf but have to say it's a wonderful device. It's given me some great data to review and improve my game and some accurate information on my club distances. If you are a keen golfer and you like to scrutinise your game this really is a must buy. So glad I finally took the plunge. Key thing is to build tagging your club into your pre shot routine. That said I often forget to tag the tap in putts but it's so easy to update after the round. Chipping / short shots aren't a problem. After about 5 rounds the software uses standard deviation to discount the outliers meaning it gives you an accurate average distance. The customer service is first rate. My course wasn't on there but I made a request and they'd created it within 24 hours. Worth bearing in mind the software won't work with Windows XP .
