Great watch. The watch and app are great for tracking activities - for hikes it shows elevation, distance, calories, route. For pool swimming, it detects my stroke and times each lap. The sleep metrics seem comprehensive. The watch also has a nice look to it. I probably only use half the functions. The only downside is the battery life, depending upon how active you are. I don't mind charging it for 1 - 1.5 hours per day to keep it going. I chose the 47 mm size as I am a male with a XL size wrist. 47 mm seems a reasonable size that should be okay for most.
So far so good. I use it with a non Samsung phone and wish all features worked but not so. Still it's a great watch with a great design and functionality. Like it alot
Really like this watch. Lots of features and good battery life. Had my eye on it a good while - when Samsung offered trade in for old smartwatch, the deal was too good to pass up.
