My micro business is engaged in the manufacture and wholesale of electronic components called Zappers designed by Don Croft. You are using a very small board and solder can easily spill onto adjacent pins in some parts of the board where it shouldn't be. The product arrived quickly, we needed it today, and it was a lot easier to use than the wider, heavier braid we used before because it was all we could get locally. Anything that makes our work easier increases our profit and our prospects for the day :-). It did. It fits into the small gaps on our circuit boards, heats up and absorbs xs solder as it should - quickly without the risk of overheating electronic components. We are very happy with it.
