Don't really know all that much about vapes but so far as I know cheaper vapouriser heat up the bud using a metal hotplate whereas the better ones blow hot air though. From what I've heard its not worth getting one of the cheaper ones.

As for being safe to smoke in your room do mean safe as in not getting caught, if so then pretty much as they don't create any odour.
dirty raider Reviewed by dirty raider on . vaporizer questions hello all, ive been doing some searching and all and have not been able to come across a quality explanation on how the vaporizer works, and what the difference is between the good and bad ones. also is it safe enough where you could smoke it in your room? lastly are there any sites that give a thorough design on vaporizers, i know it wont be great but i cant drop 100+ on something like that. thank you!
