Hey, its Kester. Count on it.

Its solder.

Works great, melts smooth and shiny no issues third roll in different diameters.

What can go wrong with solder?

Best solder ever invented

Good! The right diameter, works well. I first bought a roll of .031 and it was too thin for the soldering I do (coax connectors, 14 or 16 ga wires, etc.) This size is much better. The .031 might be the right choice for circuit board work.

Not much to say. Its solder, with 40% lead in it. Flows and wets wonderfully compared to lead free. Well worth the marginal increase in cancer risk if you use it regularly. Just remember its not RoHS compliant, so dont use it for work purposes if you have to follow RoHS guidelines.
