Zeblaze ZeBand Bluetooth 4.0 Smart Wristband
Advantages: It is pretty and it is well designed. It does everything it says it will do. You can wear it in the shower which is great because there is always a chance you might forget to take something like this off so there are no worries here! I really enjoy having this. Holds battery really well!
Limitations: App doesn't work well, always shutdowns with looking at summaries
