Review: Amazing garmin - Amazing watch the best I have ever owned. Massive upgrade from fenix 6. Well done garmin, outstanding watch
Review: Great Product! - This is an amazing watch. It is expensive, but its a flagship Garmin. Had to upgrade after 4 years with my Vivoactive 4. Chose this watch because of the MIP display, i don't want a cellphone screen on my wrist. Don't be fooled, I can still see everything i want on the watch. I've had it for a month and i'm still exploring the features. I work in a office, so not that much sun exposure. After figuring it out and playing with the features as one does with a new watch, the battery lasted me 14 days and this is with over 50km running, 6km swimming and 80km cycling. Believe with propper setup and good sun, it can last 21 days with a decent amount of activities aswell.
