You get your bang for your buck
I have had this watch for almost a month now. I used to have an apple watch and once the battery stopped holding a full charge I knew it was time to go. I will start with my dislikes on this watch. 1: the watch is not a touch screen, and while this prevents the watch from automatically starting workouts (which I encountered occasionally with my apple watch), I still find it a bit inconvenient. 2: the watch will not track your V02 max unless you start a run on the watch. I use a few different fitness apps and record my runs on them mostly, so after my fourth run I realized even if I sync my workouts on garmin connect, I don’t get a reading unless I start the run on my watch also. 3: garmin connect does not sync with fitness apps. I have used fitbod for years now, and also recently started using strava instead of MapMyRun. It doesn’t matter if I log weight training or runs on the aforementioned apps, I always have to go into garmin connect and log the workouts individually once complete. Here are the things I like about the watch. 1: the battery life! Once your watch is fully charged, it lasts two weeks (14 days) before needing a recharge. Unlike my apple watch where I would sacrifice sleep tracking to charge the watch overnight, I can wear my forerunner during the day and night. The only time I take it off is when I shower. It also does not take long to charge, I’ve charged it once in the time I’ve had it and it only took a bit over an hour. 2: it tracks heart rate, steps, sleep score, stress, naps, HRV status, V02 max, and more. It also gives you a recap once you wake up of your sleep and previous day’s accomplishments. 3: it’s comfortable to wear, and easy to adjust. It does not bother me while I sleep. Overall, I am happy with my purchase and glad that I switched over to garmin. Yes they are pricey, but you get your money’s worth utilizing all its features!

Excellent watch for runners.
Excellent watch for running. Previously owned the fenix models but this one is better for running and metrics.

Excellent watch for the price. I use it for running, biking work outs. The only down side is that it seems to get disconnected at least once a week or so and I have to keep re pairing it. I did not have this problem with the 235. Good watch though and much improved.
