im looking for a vaporizer that is small and portable, that i can also use in groups... i figured i could use the thermovape as long as i had like 8 sets of batteries at a party with 5-8 people, what do you guys think? i like the thermovape because of the build and the durability, but it doesnt have a long battery life, i like the solo for the milky hits, but the battery is not replaceable, unless you send it in and its like 100 bucks... what do you guys think?
