I got a Vapor Brothers and it works great. You might not have it hot enough. I know the intructions say to put it on high for a while and then back it off 1/2 way but that seems too cool. I've found that mine works best when the little white line on the knob is pointing straight up or about 1/2 way bewteen 12 and 1 oclock . There should be a definite red glow coming from the heating element. When you exhale you should see a big cloud of vapor. It looks just like smoke at first but doesn't smell and disappears into the air. Play around a bit with it to see what works best.
