I honestly love mine, and for some reason it's one of my favorite things to blaze with because it's really small, compact, and can go anywhere.
Just slide the cigarette bat out of the chamber, and press down with the cone end in the other part and light up. looks like a cig, only nobody torches a cig the whole time so that's the sketch part
