Today I share my own experience with FastTrack Refkex smart band. This is a feet Ness band. Inwas used this band more than 6 months but when I was using this band I faced some critical problems. First problem is battery backup. Battery backup is very poor in this band. Charging time of this is more than 3 hours but after full charged of this band, this is work only for 1 days. After 1 days, battery is totally empty. This is a big problem. Beacuse others band smartwatch is mote battery backup. Like mi band has 1 month battery backup but this band has very poor battery backup. I don’t recommended to buy it. Thank You.
