My first experience with a fitness band began exactly a week ago when I bought the Garmin Vivosmart at Sitex.
This was after much evaluation of the options available in the market. Essentially, wearables fall broadly into two categories — activity tracker and smartwatch. I wanted the look of an activity tracker (which I think looks cool) with the features of a smartwatch, especially notifications from smartphone.
The Garmin Vivosmart fits these requirements nicely. After one week of wearing it, I must say that its features have transformed my life in several ways.

Wearable electronic devices for fitness shipments are forecast to reach 68.1 million units in 2015, down from 70 million units in 2014, according to Gartner. This temporary dip in sales will be driven by an overlap in functionality between smart wristbands, other wearable fitness monitors and smartwatches.
