Mi band 4 by Xiaomi is a good piece that you might need for your daily activities and health check probably. The Mi Band 4 features the same design as the Mi Band 3 but here is why I can suggest you swap or change from version 3 to version 4. Xiaomi release budget wears every year to give users something to rely upon if the Apple, Samsung, Google, Huawei, and other high-end smartwatches cannot be afforded, the Mi Band 4 is a good deal if you need a well-equipped mid-range wear.
