What are you looking for in terms of features and what is your activity level? There are so many of them out there.Anyone have thoughts on those fitness smart watches? I'm thinking about getting one.
My personal favorites are the garmin fenix series, but they're mad expensive and unless you're racing or at least really active it may not be worth it.
I personally find Fitbit to be pretty good value. My biggest needs were long battery life and built-in GPS, which the Versa and Charge 5 deliver. I can go a week on one charge and the GPS works. I just spent 8 days in Europe and didn't have to charge my Fitbit once, got back home with 9% left. The GPS is not as good as the Garmin watches, but it gets the job done. They also have a pretty user friendly app to log calories and monitor your health metrics.
My least favorite by far has been my galaxy watch. The battery lasted 30 hours if that. It doesn't serve me a purpose if it's constantly dead or on the charger. I've heard apple watches are the same.
There's a guy on youtube called DesFit that really goes in depth on all these devices and puts them through the ringer to test them. I really recommend watching his reviews to find what you like.
