Familiarity: I gave it as a gift but have feedback to share
I gave this to my fiancé for Christmas so she'd stop stealing mine for her trail runs. The main feature she needed was a long battery life - she wore a previous version of this watch for 95 miles of trail before the battery died. This watch allows for 100 hours of tracking if you select the lowest accuracy setting, but you can opt for better accuracy with a shorter battery life as well. Nice to have options for different types of training/adventures. This watch looks bulky, but she actually hasn't had any complaints or discomfort with that even given her small wrists. Total win!
