I'm posting this to hopefully prevent anyone from getting injured. I owned a couple of the Indulgences and I have to say this is a device waiting for a major indecent to happen. My first ones just had an issue with over tightening causing the positive post insulator to break from over tightening a atty or carto on it. I just had my first hard short which continued when the button wasn't being pushed. I lucky just burn my finger tip badly and wasn't severely injured. I want to say if I wasn't using a Panasonic CGR18650CH I probably would be in the hospital from a catastrophic failure causing venting or even an explosion. These are the same batteries used in the AW IMR and Callie Customs batteries. I got my battery out of the device and it remained room temperature. I checked the battery to make sure it wasn't the cause and it meters out just fine and is in good condition. I'm not sure how come this happened, but I know it was firing with out the button being push, which makes me believe the switch is defective. I just want people to be careful and not to get hurt. I recommend to anyone using this device to throw it in the garbage. This failure was not due to any kind of user error and it just seemed to happen out of nowhere!
