To set up time in Mi Home app region Select-China. With the region of Russia it does not connect to the clock, they are not on the list. 2 batteries included. Every 30 minutes blinks inverting flowers for a couple of seconds. Yes, the display is electronic ink, at any angle the contrast does not change. There is no illumination.
Delivery-just under two months. The box was worn, but there was no damage on the clock. The clock itself-liked. Quality of performance and appearance-do not complain. Quickly synchronized with the proprietary application from Xiaomi. The screen is very contrasting, the readings are easy to read. I recommend both the watch and the seller.
