I got fitbit charge hr few days back, after using it for 4 days I an writing this review, I bought this after lots of research about fitness band.First thing the big disappointment is it's step count which is very inaccurate even when I am not walking it is counting the steps just on movement of hands and wrist. Its sleep tracking is also inaccurate, it doesn't track the sleep during day time like short naps during day. Its battery life is very poor.I strongly recommend users not to go for this product.
