You should have gotten cartomizers. You might also have one atomizer. While you're charging it up, go to Youtube and look for a video on how to fill your cartomizer by the "condom method". Take your atomizer and screw it on the end of your kgo. drop 3 or 4 drops of juice into the top of it, right in the center. Wait 30 seconds. Put the plastic mouthpiece (drip tip) into the otp of the atomizer. Push the button and vape. If it tastes o.k., or if that's the only juice you have, fill up a cartomizer using the condom method. Screw the cartomizer onto the kgo. Screw that metal cone thing onto the kgo. Put the drip tip into the top of the cartomizer. Push the button and vape. Dont let the cartomizer dry out. When the vapor gets weak, after 10-20 minutes, drip some drops through the drip tip to re-wet it. Tilt the cartomizer when you do this so the juice drips down the side and not into the hole in the center of the cartomizer filling. Don't let the cartomizer get too dry. If it does, it will burn and taste nasty and you'll have to throw it away.
That's about it. You should have an atomizer, one or more cartomizers and a drip tip. The atomizer is the small metal tube with a heating element in it. The cartomizer is a longer metal thing with two plastic covers on each end. The drip tip is a mouthpiece to use on the cartomizer or the atomizer. If you have anything different than those things, let us know what they are and we'll tell you how to use them.
If you got just an atomizer and cartridges with foam stuff in them, get back on line immediately and order 2ohm cartomizers. Cartridges are useless. You're better off just to drip juice straight into the top of your atomizer.
