Review on WYCTIN 1.0Mm 50G 60/40 Tin Lead Soldering Wire Roll With 1.8% Flux For Enhanced Performance by Joshua Carter

I have had this solder for over a year in my tool box. Needed it yesterday for a small soldering job. This stuff would not flow on to the wires and what was being used for flux did not smell like any flux I have ever smelled in the past 60 years. The stuff left a gray dull look to the soldered wires like a cold solder joint. No amount of heat would correct the problem. This stuff was a waste of money. It went in the trash can. Luckily I still had a little piece of some American manufactured solder and was able to finish the job.
