AGAIN, NONE OF YOUR EXAMPLES ARE PORTABLE... HOW CAN THEY BE COMPARABLE? please, which one of your examples fit into ones pocket and do NOT require and electrical outlet to operate? LMAO
Rfmk is a company that sells ecigs more or less. There is no Ecig on the market that will vaporize plant matter. like another poster said "those are all plug in models" You can try to twist the argument but truth always wins out.
BTW, no one is talking about burning anything, these are vaporizers and do not burn the material, whether were talking raw plant material or hash.... I really think you may want to do some more DD on this....
