Summary: I got this watch in December 2014. The watch did all it was advertised to do, and I was a happy camper. However, 5 months later, the watch gets into black screen and turn itself off. I went to the forum, tried rebooting, factory reset, charging three nights.
Summary: Love the color of the watch. Super easy to use. You just hit the run button, and you're ready to go! Unlike my old Soleus Fit watch, this one's GPS is ready to go almost immediately. No more waiting 5 minutes for a watch to catch a signal! Heart rate monitor is pretty accurate.
Summary: Great running watch. Watch is light and you barely notice wearing it. Screen is easy to navigate, lots of information at the touch of a finger. After your run, easy to upload information to Garmin Connect App or to computer with so much information that will help your running advance!
Summary: upgraded from 610. best pros: lighter, skinnier, first gps i've had that feels like a regular watch. wristband is also more flexiible. much faster sat acquisition, within 5-10 seconds. more intuitive programming, i.e., intervals are just one tap away from run page now.
Summary: My old metal backed 610 died and I needed to replace it, so I got this. I can't be happier, lighter, more features, easier to use. I really like the fact it does cadence without any add-ons, I didn't realize it did it. I picked this over the 220 for the wifi sync, which works flawlessly.
