Summary: The watch does what its supposed to do. Getting the initial signal has been touch and go. Once connected the watch works flawlessly. I connect the watch to a Mac. The autorun feature does not work so the software must be launched manually. The software is easy to use and provides the right amount of information.
Pros: Accurate, Easy To Setup, Easy to use, Intuitive Menu, Large Screen
Summary: My daughter and I both bought one of these for a local race (I ran the 1/2 marathon, she ran the marathon). It was a good tool for helping with pace, etc., but both of them were off by 0.01 miles/mile. For short runs, not a big deal, but that's an 1/8th mile error for me and a 1/4 mile for her marathon. I'd recommend it for shorter runs and recording casual runs, but not for serious runners.
Summary: This watch worked well for purpose...showing distance and such on trail runs. The Garmin software is also helpful, showing your route, elevation changes, speed, etc. However, I found the watch lacking in design (bulky, certainly not stylish) and multifunctionality (lacking several functions of most basic sports watches). I ended up returning the watch.
Pros: Accurate, Intuitive Menu, Large Screen, Reliable Reception, Simple Controls
