LOL So true. I do remember one of my 10ml bottles of Waffle had leaked. It was weird too. There was flavoring powder all over the bottle. The alcohol had evaporated.I just got a package from them, and I used DHL
I had 4 leakers in the batch. Glad they were enclosed in plastic.
That's the first time I have used DHL, and I'm thinking the air pressure from flying is the culprit.
I've heard of others having that problem with their mods, just flying commercial.
When I flew, I didn't notice a problem with my gear ... maybe I didn't go far enough or fly high enough
Just thought I would mention that,... but from now on, I won't be in such a hurry
