I buy this fitness band about 15 days ago at first the band works fine and its accuracy was very. But after a week I noticed some problems that its accuracy is is getting low and the battery backup is not that great it takes more than 5 - 8 hours to charged fully and doesnt last more than 2-3 hours.
I wear these fitness band usually , when Im doing workout. And I found that the product is not water resistance cause when my sweat are touch to the band, the band goes shutdown, and it took me 1 whole day to recover this fitness band from dead.
That product is not worth of my money, its the worst fitness band that I ever buy.
