so im getting dangerously low on juice because my order, which i paid for speedy shipping on has taken almost a week now.... i went to the gas station to check out the Njoy carts. which screw right on no issues at all. however i am now gonna call these thing NOJOY because they taste like chemicals, with ZERO tobacco flavor whatsoever. they actually made me gag and want to barf. they are NOT refillable in any way. the little plastic caps you can normally remove from cartomizers are GLUED IN. seriously lets put glue in something that is gonna heat up that people are gonna inhale...that will work great. if your ever getting tight on liquid just smoke less or something because omg this stuff is HORRID!
