    Caution - Post Broken
    I purchased the watch in 2018. It has been a great watch and never abused. Use it mostly for biking, running, hiking, and working out. Yesterday the watch just feel off my wrist. I thought the strap pin came off but the post where the pin goes into broke.Internet searches show this is a major problem and happens to many people.Garmin set up a website to rectify the situation. Currently, based on my serial number, they are offering a refurbished replacement for $130. I find it steep. I have owned dozens of watches and never heard of a post breaking off like this making the watch unwearable.I have had it nearly 5 years with only minor required reboots and upgrades. Maybe I am lucky for it to last this long but never expected it to break in this manner. Based on the design flaw, I do not recommend the watch. I am going to try the repairs listed online using superglue or jb weld.
