The battery lasts a long time (the 1st charged from the moment of receipt, 26 days have passed so far, not charged). It helps me control my heart rate and blood pressure is the most important part. And it helps me move by checking how many steps I've walked each day. I want to share with all bracelet sizes because if I want to buy one, do I check if it fits my wrist? So here the strap has ten holes and there is a 1/4 inch gap between each hole, if your wrist is 8 inches you can fit in the last hole. Hope this is of help.
