I've never broken a glass tank, and though I ordered some bands, I kind of hate them and don't use them (maybe if they were more elegant?). I'm not a dropper, though. The one time I knocked over a mod+tank onto the floor, it happened to be with a Nautilus Mini with a stainless steel sleeve, so no problem (... except the magnetic cover for the batteries on the mod fell off, the battery flew out, and the casing was torn in the process).
HOWEVER, a lot of the Kayfun Mini 3 clones I have came with a stainless steel tank (as well as glass) and I do use several of those in that SS configuration. Still haven't dropped/knocked over any of them yet, but I kind of like the feeling of invulnerability. Sort of like being a superhero. of vaping! okay!
Hopefully you didn't jinx yourself! I had never broken any phone screen before today! Maybe I should change all my tanks that have SS options!
