Summary: I have owned two of these and as a GPS device it functions well. However, both of them had terrible issues downloading data to Garmin Connect. Garmin recently introduced an updated Garmin Connect.

Summary: while the forerunner 310xt works well as far as a GPS watch for gathering data on my runs getting that data on to my computer with the ANT sick is a different story. it is almost a full time job to get the 310xt and the ANT stick to communicate.
Summary: When I first got the product it worked fine. Although there was a bit of a learning curve to learning which button to push in order to get the result I wanted I soon "got it" and navigating the interface became more fluid.
If you want to consistently connect with your PC, don't bother

Summary: As a GPS it is decent. But the connection with the PC is awful. Simply awful. They use a USB with a software program called ANT Agent. It is totally inconsistent, becomes confused with my wife's 310XT, connects slowly, if at all, and when it does, it takes forever.
Summary: I had the Garmin Forerunner 305 for over seven years. Fantastic, sturdy watch. Loved it! Don't know what happened here with the 310XT?? In less than a month it stopped working and I sent it back. Maybe it was a lemon, but I didnt get a replacement.
Summary: I used this item three times, the last time I turned it on the screen had lines going through it. This makes it very difficult to read. Has anyone had this problem? Is there a fix? I tried resetting it, that didn't work.
Summary: I have had my Forerunner 310XT for two weeks now, and I have been completely unable to upload any of my workouts to the online Garmin Connect system. The whole reason I purchased this product is because I wanted a tool to help me track the workouts I do in preparation for triathlons this summer.
Summary: I had this for 3 or 4 days and then I returned it. The USB Ant stick did not work easily. I have a 305, which directly plugs into the computer. I have NEVER had any trouble downloading from it.
