These things are fantastic they do require a little maintenance daily likee you would any ******. This is a ceramic disc at the bottom of a ceramic chamber with 4 vent holes in the middle to draw air into the chamber. Make sure to have some 91% ISO and stiff Q-tips to clean the inside. Hold upside and fire sesh mode this will help any reclaim and or residue come out easier. once you see stuff flow down use tthe ISO and q tip to clean. fire again to dry out any of the ISO and wait like 5 mins before loading it again. The flavor and amount of vapor production that are given from a very small dab amount is such a pleasant experience. This is not for the lazy toker the chambers can last months if cleaned properly.
