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

This product was used in electronics construction. While it did finally work, the heat to get it to flow properly was excessive with damage to the soldered parts at times. It would also always cool dull gray and crystal like in appearance. One of the worst solders I have ever used and I have done electronics design and construction all my life. As a side note, the soldering was done with a temperature controlled iron so that it did not overheat.
