I used YuFit Band about 2 months. But the accuracy of this band is not accurate It sometimes counts more steps and sometimes less steps. Battery backup is about 15 to 17 days, it is less than other Fit band in this price range. I also has a display which gets scratched quickly. The strap quality is nice. App support is not good because the app is not free. I lost this band therefore I can’t share all its quality. But I think It’s not the best.
