I was using mi band 2 from ciaomi till last month but then the band fall into water and did not worked again so I bought this Misfit Ray fitness band initially it fell well in hand and stylish but after a week or so I sgarted realising that the accuracy is not what I would have expected I used to have sleep of around 7-8 hrs from 11: 30 pm to about 7-7: 30 in morning but the band for 80% of the time shows that I have slept for over 10 hours which is impossible.Mi band 2 was a far better in accuracy and in such a high premium price one can not expect to have issues in accuracy moreover the steps counter is no exception it is just misleading the day when I walk for long distance the band gives data that I have not even walked a km and the next day when I am travelling via my car I am getting data as that I have walked 3-4 km I mean I just cant trust the fitness band for my fitness and would not recommend it to anyone
