Great battery, great accuracy, very hard to preserve data in Garmin Connect and Strava.

Summary: I have downgraded my review after upgrading it (see my original and then previously edited reviews below). The reason is that Garmin has a known issue with data not syncing. I have spent a couple hours trying to sync one stupid 3 mile run. I gave up and manually entered the data.
Nice, but could be better for the money you spend!

Summary: Indeed it measures well speed, distance, BPM. The screen is pretty big, and it is easily customizable. The altimeter, which is one of the features that makes it more expensive than the 310XT, doesn't work that well, it ranges almost the same everywhere I am, around 700m.
Summary: I recieved this watch for Father's Day this summer after using a 205 for about 4 years. The 205 was great and collected rock solid data but didn't have an HRM and I couldn't use it in the water for Tris so I got the 910 Tri bundle.
Summary: Prior to this Garmin, my husband and I had Forerunner 305 units. They were a great work horse type of Garmin, but we wanted something for open water swims. We have become more and more frustrated with the ANT stick, which never seems to work unless we restart the computer, and the charger, which...
Summary: I purchased this device in June and found that the distance and elevation were unreliable. The distance is consistently longer then a older 305. The elevations are all over the place, I am not just talking about 20 feet off they are off by more then a hundred feet.
Summary: I purchased this watch at a local running store on January 29th, 2012. It worked well for the first couple of months. Then, without warning and without firmware updates, it began to experience difficulty in keeping the correct date and time when powered off.
Waterproof? I am worried about longevity after mine fogged up and died

Summary: UPDATE May 14, 2012: I am on my 2nd 910xt. During my Olympic Distance triathlon last week I noticed a fogging screen again!!! I have only had the new watch for a month. What is going on? I really want this watch to be waterproof. Considering my options.
Summary: I was really looking forward to this watch as a replacement to my 305 as I wanted the vibration alert and the improved startup time (as my 305 takes about 5 minutes to lock satellite) as well as some of the other new features.
