To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was looking for a simple to use and small fitness tracker just for steps, light exercise and sleep. The Mi Band 5 was an excellent fit for me. It was easy to use and fast to charge. I downloaded the app and started using the device the very evening I received the device, to track my sleep. The information provided by the free app was very useful for me. The battery life is also excellent, since I only use it for step tracking and sleep, by the second week (14 days) of use, it still had about 30% charge left. There are also many accessories available at very reasonable prices (read as really cheap) for this device. Really happy with it and glad to have bought it from Amazon! Thank you very much :)
