Summary: I purchased the SG5 some time ago and I have used it over 50 times. Initially, I was pleased with the product, but I found the buttons and selections not very intuitive and battery life rather poor.
Summary: Just keep in mind you have to repay the membership fee every year or you SkyCaddie deactivates the courses you have downloaded. It just happened to me and I called SkyGolf to confirm. $50 per year for the multistate membership is kind of expensive.
Summary: The SG5 has worked at all of the golf courses I've used it at. I've had some issues with the yardage being off but most of the time it's pretty accurate. Battery life is pretty decent and will certainly last a round or two. My issue has to do with price and the ability to customize.
