Xiaomi has released a picture on which hints at the upcoming announcement of the Mi Band 1S fitness band. The teaser also says in Chinese "Good Things Happen Tomorrow," with July 22 date. If the company keeps similar price tag, it could have another winner.

The previous model was shipped in over 6 million units and was priced at only $12. For that price, I seriously doubt you'll find a worth contender. The device measures your sleep and tracks your health and workouts, and works with any Xiaomi smartphone. The good thing is it can run up to 30 days.
