I work part time for the creator of the Touch and Flow. What the guys said abot getting the last drop out of the needle is correct. I normally just blow on the glass tube til the tube is empty.The needle does get clogged from time to time from the melted plastic.Just stick the needle in the bottle of liquid cement and it will normally melt the little clog, Sometimes you may have to give the tube a little blow. Myself I prefer the Ambroids glue over the Tenax. The Tenax runs a little to hot for my liking. Thanks for using the Touch and Flow its a great tool.
