1. Walking on rocky terrain
You know that old saying about bread always falling butter side down? Well, in a vaping context, devices that get dropped on mountain trails always hit rocks on the way down. You could be forgiven for thinking that there are magnets in craggy rocks that pull your device inexorably towards them. Sadly, this means that if you drop your vape on a mountain trail, it'll definitely hit a rock, and your tank will almost certainly break.
Never tackle rocky trails while holding your device. Keep it somewhere safe, and only vape when you stop for a breather. Place a protective band around your tank, and always carry a spare e-cig with you. Better still, invest in a shockproof device. A vape with a lanyard would also prevent you from dropping it.
