The only issue with inverting is being careful and to always hold the unit while it is inverted. There should not be any other issues. And if yours breaks, I can fix it or replace it. :)
Email Vapefiend and ask the price to repair an EVO that you purchase from them. They charge extra if you buy it somewhere else. I can make you a 220v refurb and repair it, but you would have to pay shipping
Unfortunately no. The container for the flower would have to fit into the bamboo at the same depth and also the thickness of the glass would need to be tested. Vapexhale never got around to engineering one.
