Just like I stated a few weeks ago, battery life is bad, need battery blocks and charging cords. At least the RFID still works when the battery dies so it functions like a normal magic band.
It won't function like a normal MB. Dead battery means ride photos won't be identified.
Based on the few posts battery issues won't affect a typical guest. It affects hard core bounty hunters. Those guests should bring a battery block.
