Bought this a couple of months back and I've been using it and lending it to friends constantly. I've been really impressed its easy to use and incredibly accurate we used it at my club to measure out distances for a golf masterclass one of the top 100 golfers on the world rankings was giving and he used a Bushnell to get his yardages anyway he was very impressed with our machine as it matched exactly his distances.
As for the golfbuddy itself its always impressive when you go to a new course and the golfbuddy knows where you are and which tee your on its numbers are easy to read and the green, front, back and center distances give a very accurate picture of where the flag is (although you can also move the flag yourself to give a precise distance)
The golf buddy is also capable of keeping track of your stats both scores and your playing habits ie fairways hit bunker saves putts in regulations its all a bit nerdy but gives a really good overview of your golf and where you might want to focus your practice.
Its easy to use with both button and touchscreen operation and really its pretty idiot proof and most of the time you'll simply look at it to see what info you need.
The website took me a little over 40 minutes to update the software and the courses on the golfbuddy and so far I've not found any courses missing from the UK that I'm likely to play including some pretty obscure Scottish courses it does hold 30000+ after all.
All in all a great device that works, but is easy to go into in massive detail if you wish or simply read if that's more your thing. Oh and its a one time payment as there's no annual membership. Highly recommended.
