I received it quickly, as promised, today. I dislike the tiny, tiny manuel. Which I cannot read. Therefore, I am trying to figure out how to charge it. I have it plugged to a socket and waiting for something to happen. It has been 3 hours. I tried to get some of my co workers to read the manuel, but too small. Maybe I have to plug their USB charger to a PC? UPDAYE: This is the second day with the watch. Still trying to figure it out. This morning I synced it up with my IPhone. It showed I slept 5 hrs with 3 hours as a light sleeper... impressive. I cannot figure out where the blood pressure section is. I will give it a week and come back here and leave another review.
