Iam a fitness freak and I used to watch fitness related products online. Iam very impressed by fitness band and on searching I found m3 band which is very cheap compared to original m3 band from MI. I thought it would be as great as original mi and I purchased it. It cost me around 350rs but the original band has an amount of 2500 rs. I ordered this from Amazon and received it for only 350rs. The problem with this band is it is super inacurate. I compared its heart rate monitor with standard instruments and I got very bad results. The blood pressure monitor is also not working well. It is just showing random values every time. It should be connected to yoho sports Android app but it has lots of connectivity issues. Many time its Bluetooth not works well. My main aim is to track my fitness activities but it is not good for that. I end up with buying original which cost me 2500rs. I just wasted my 350 on this band.
