Best Fitness Tracker So far
I did a lot of research before purchasing it.
Now coming to this product:-(using it with LG Nexus 5)
Pros:-
1. Colored screen whereas fitbit charge 2 has black and white
2. Touch is smooth and screen is bigger
3. You can play music without carrying your phone through your bluetooth headset - a rare and must have functionality
4. Battery life is OK. No need to keep it always syncing with phone.
5. Sleep tracking is OK but not required. It is just a publicity stunt. Instead use that time to give rest to your wrist and you can charge it during that time if required.
6. Automatic Activity Tracking works great
Cons:
1. Since, screen is big. Everyone notices it at first glance - you can show it off. yeah. Also, it consumes little more battery.
2. Other than that nothing.
