The other day I had it in my pocket and when I opened the car door it hit my pocket. Later I noticed the tank was sitting crooked I tried to fix it but it wouldn't sit right still there was a gap between the tank and mod. Today I was messing with it and the piece that connects the mod and atomizer came right out. It still works if I push it back in. Any suggestions on how to fix this or is it dangerous for me to be using it this way?
