Great features but falls short!

I was very excited to upgrade from my Garmin Fenix 6S to the Fenix 8. However, I was frustrated with the treadmill and running activity features as the heart rate was completely inaccurate. It was spiking within the first 5-10 minutes from the 130's-140's to over 180's and stayed there for the better part of my treadmill run, specifically, before dropping back down into the 130's-140's. Garmin did exchange watches for another new one and the heart rate was spiking the same way. I reached out to Garmin and they sent the HRM200. This has seemed to have solved much of the issue. It's frustrating that the watch is SO expensive and isn't accurate where it should be! Hopefully the update will help to balance the heart rate metric to reflect the correct heart rate.

A comfortable watch with a small wrist band

I originally purchased a Fenix 8 - 47 mm watch. I loved the features but was a bit too bulky. After a few months I broke down and got the 43 mm. This is much more comfortable, but I can barely get the wrist strap closed, and the velcro band barely fits over my hand. I would love Garmin to make a longer band for this watch. Again love the features and can now wear it continuously.

I like my new Fenix 8 - 43mm. Now it has a flash light and diving features! Not sure I like the golf activity changes vs Fenix 7 - but we will see. Set up was pretty seamless.

I've been a garmin forerunner user for about 15 years. I was debating between this fenix and the latest forerunner. While I'm sure the forerunner is great I couldn't be happier with the Fenis 8. It doesn't feel bulky, great battery life and the technology and features made it a seamless transition from the forerunner. I love the look and everything about the Fenis 8

This was an upgrade from my Fenix 6 Pro, and it is incredible!! MUCH easier to navigate, improved features and tough, but extremely stylish!! I beat the heck out of my 6Pro over the years (never took it off), and feel that this one will take it too!! Highly recommend!

Great watch

Great watch! Really like it! Cool features! But sometimes it reads my heart rate completely off during activities! Which is really annoying at times! But other than that great addition to my life!
