hey guys. using the hash oil cartridges from www.oilonthecoil.com on my 510 blu cig knock off . works fucking awesome, BUT it comes with that same mouth slip thing that omicrons come with. i like it of course, its chill... but when i use a metal mouth tip on it, (aside from getting a little warm) it gets reallllllyyy oily (the bottom part that clicks in over the hash oil section above the coil)... anyone else having this issue / anyone have tips to use a mouth tip with these carts that goes INSIDE the them? i know you can use the glass ones, but i have some dope metal ecig ones. thanks
