i think i might be sticking with boge. my ikenvape platinums make me feel like i'm going to suck my eyeballs in. that's after punching through the material behind the air holes above the threads on the 510 connection. after opening them up, it's still the toughest draw out of any vaping product i've tried to date. tried 4 of them out of 4 different boxes. all the same. shame i bought like 7 boxes on account of such rave reviews by bad. i never do stupid things like that normally...
