Until I got my BilletBox, I didn't used the Diver I had ordered for this purpose... So when Mr Postman bring me finally my BilletBox this morning, I put the Diver inside and thanks it vapes so great 
But it also leaks from the bottom of the Diver and I was wondering what is the best trick to prevent this. My cup seems to be tight fitted
