So far I've been using the watch in my training for the February 15th marathon in Austin, and I'm very pleased with it. It's lightweight, the screen size and quality make it very easy to read, and I haven't had any problems with the GPS.
So far tis great - I tried to do training for a hyrox race with my apple watch and hated that I couldnt switch between run and hiit - if I put it on run then I would get my pace that I needed but then as soon as I did the 1km then hit a station the pace was messed up. If I put it on HIIT then I dont get my running pace, but I get my heart rate zone info I want. Now with the Amazfit I can put it on hyrox training or for my sims I use the hyrox race mode and its so so nice to help track and make sure I am keeping up with the pace I am shooting for for the runs and the stations.
