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 purchased this watch in December 2012. Shortly before the year warranty was up, I had trouble with the charging, but thought that I had resolved that and did not contact Garmin during the warranty period. Since then, the watch has not reliably charged--in fact, even when I can get it to charge, with great difficulty, it later discharges if left on the charger. I have had Garmins for years, and almost purchased an older 310 as a replacement.
Summary: As a previous Garmin Sportswatch owner, this is definitely the best to date. Over the years, I have owned many different Garmin models and some of the competitors, but this outshines all the others. If you are looking for an accurate, durable, reliable and great looking Sportswatch, then look no further than the Garmin Forerunner 610.
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.
