1. They look good , but how long do they last ? I had 3 pen style models that all died in a month ! So I'm looking for a battery that will last much longer . That's more important than clouds !

  2. Pretty Cool video I Have Two Silver Pen battery’s just like the one you showed in this video and I thank you because I didn’t know if it was just changed color for looks or actually temp adjustable
