I have owned a few Samsung smart watches but I will say this so far is the best that Samsung made. It has the brightest screen, the most feather compare what I have before. It's been a big challenge for me to learn all the functions but that's the fun part of playing with my new watch.
I love the watch, I am really happy that the the edge and ridge of the design keeps the glass from cracking as easily as the 6. I don't like the manly looking watch bands. There should be a slimmer more feminine version of the band for ladies not just colors. Other than that it works great, keeps my steps, monitors my sleep, and reminds me to take my medication daily. I would recomend this watch to friend and family.
Only had it for 2 weeks and I'm getting about 3 and a half days on a fully charge. Nothing negative to say this far. The best Samsung watch to me in my opinion.
