My freind got this band Intex Fitrist Health Band 10 days ago. He buyed it cause its related to fitness and looks cool. But after some days he was like a complaint machine of this band. I tried it . its really bad looks great but features sucks . display is poor , and believe me it doent give the calculation of any energy loss by us . and I dont want this band for my fitness calculator. I must use it as a hand watch.
