This band only looks good and having a brand name of the fastrack tge peoples only goes for this option other wise ther is no chances of selling this band it does not work properly like lenovo hw01 and mi band 2 only its prices are high than its limit because the product mi band 2 having the heart rate moniter and digital display and having good features is works good than the fastrack smart reflex band it, s only for the name smart the band has bad youtube reviews and only tge strap quality of band is good and it does not sync automatically with the watch it is not so good as we expected from the brand like fastrack . Its not good as par my opinion other wise all rest to your.i recomend dont go for it.
