Best Budget Sleep Tracker: Xiaomi Mi Band 4
Not everybody needs a super expensive sleep tracker with all of the bells and whistles. If you are looking for a reliable way to track your sleep without breaking the bank then the Xiaomi Mi Band 4 is a great option.

Are Sleep Trackers Accurate?
Sleep trackers can help you understand your general sleep patterns, but they are still at the very early stages of accurately tracking sleep.
While the using the recommendations of a sleep tracker are definitely better than using nothing at all, anything short of an overnight sleep study performed at a sleep clinic will not be 100% accurate.
