Its always a coin toss... *knock on wood* I have only broken one
tank in two years of using glass
tanks and it was a 22mm standard Zombie that I had used for close to a year. Hit the parking lot getting out of the truck and it was a heartbreak moment. I always take two devices when going anywhere, also have a clear tube, spare cartomizer and 30ml bottle of liquid in a baggie in the glovebox so i can rebuild a
tank if needed and be back in business in a few minutes.
