Summary: I have had other Garmin heart rate watches before and they worked well. This model is simply an awful device. The heart rate never reads accurate and is 20 to 30 bpm fast, which means all the data related to the heart rate is erroneous. I have looked for answers to this problem and simply could not find a satisfying solution. Apparently there are many similar complaints which Garmin has been ignoring.
Summary: I got the refurbished model and had no issues with it. Easy to setup and just start running. The refurb model you wouldn't be able to tell that it wasn't brand new. I haven't synced to the computer so I can't speak to that. Solid band on the watch. The display took a little time to get used to but once you get the hang of it there was no problems.
Garmin Forerunner 610 GPS Watch GPS Receiver - The best!!!
8 March 2014
Summary: Why I love it: THE DATA YOU GET AFTER A WORKOUT. The mygarmin website has so many cool features, I'm much more impressed than the website I used for my android running GPS app (Runkeeper Pro). The watch is super comfortable and the form factor, while a little big, is more than practacle. SO why 4 stars? It's a bit hard to set up unless you've had a gps watch before. You have so much functionality with the watch, it takes time to figure out how to use it.
Summary: I bought this watch for my boyfriend for xmas and he loved it. He's been telling he wanted this watch since it came out. He uses it everyday like a personal watch and also when we go out for runs and marathons.
