Today I am telling about Misfit Ray Fitness and sleep tracker. This brand usually for track our sleeping. I was used this product for 2 months but when I was using this, I saw that this brand not measured exact time of sleeping. Many errors presented in this band’s result. Price of this brand is more than 5000 but in this price range, you have many better options. Mi band 2 is very good band in low price compare to this. Misfit Ray Fitness band has also very low battery backup. You can not able to using this band more than 2 days. I faced this type of problem in this band. So guys avoid to buy this band. Thank You.
