I bought MI hrx band 3 months ago and I have been using it since November. The good thing about this band its weight is very low. It is not heavy so I feel comfortable in this band. But it doesn’t work fine. It has step counter which tells wrong things. Looking of this band is like a Chinese cheeper bank. It looks like kid’s toy. It has one button on its front surface, which looks weird. That’s why I don’t wear it now. Battery backup of this brand is quite nice. I have to charge it twice in a week. It has only two or three features. Overall I don’t think it’s a value for money product for everyone. it’s good for childrens.
