I'm looking for a stealthy on demand and battery replaceable vaporizer and I'd like to know if you guys have any recommendations. I have the Mighty, the Sticky Brick Jr and the Omnivap Ti. I really want a stealthy vaporizer on demand with replaceable batteries and I'm certain I'd buy the Grasshopper If I was from the US. Problem is I'm from Brazil, so I really don't want to risk sending it back to the US. I'm torn between 3 options: 1) Wait for the Grasshopper to become reliable (maybe never?) 2) Buy another stealthy on demand vape, like the Firewood 4. In this case, I'd wait for the next Firewood, I guess. I'm also open to other suggestions. 3) Wait for the announcement of a good vaporizer that can fit the stealthy on demand with replaceable batteries criteria. What do you think I should do? Any suggestions? Thank you so much.
