I am very very dissatisfied because the mouth piece got so hot when i tried to pull for my first puff that i couldn't hit it. And it won't stay charged and the juice leaks out into it onto the gold battery prongs where the mouth piece connects to the battery.. I think you all shoud check the Boulder out before one ends up blowing someone's face off.. now im out my money that I paid for it I know it wasn't much but I was excited because for the first time I decided to get help quitting smoking and chose to buy from you and it isn't a good product at all.. i have been smoking since age 14 so this was a huge deal for me... I don't make much money at all 3 days a week cleaning toilets so I cant afford to buy a really good one nor can I afford to buy another one period.. so thanks for nothing..😠
