I have to admit that I'm pleased with the performance of the Garmin G10, although in the early stages of use I'm satisfied. The gauges seem pretty accurate for the most part. I don't really care about the "extra" features of many golf GPS units, but this one gives me little more than the basic functionality I'm looking for. It's small but legible, easy to use, attaches to my carrying case, and has a very reasonable battery life (about 4 rounds on a single charge. Not bad). But as I've found with many golf GPS units I've used before, time will tell.
