Works as advertised.

This is the best flux I have tried to date. It is the best product I have found to solder nickel coated copper.

Good Stuff!

I taught several soldering classes in the Air Force, and I've found that a thinner liquid flux turns out a better and more reliable solder joint. It important to use the least amount of heat for the shortest amount of time and the using a liquid flux vs a paste will help you accomplish this. The needle tip is a plus too. It allows you to get the flux in tight spots without getting it anywhere else. Hope this helps.

I recommend this flux

Good flux. True, the package did not arrive, and I bought it elsewhere.
