I have this for assembling/repairing Ham Radio Electronics (HAM). Four (4) tubes of 63% tin and 37% lead rosin core solder works best for me as it has a lower melting point and easier flow characteristics than lead-free solder. The dispenser cap minimizes skin contact (wash hands after work). The tubes have a pocket clip which I found useful to keep the tube from rolling off the work surface. I thought this was a good deal and added tubes to both my ham radio emergency kit and my home workbench.
