Review: Great rosin. - flows very well, would definitely use this product again. Highly recommended
Review: Excelente pasta para soldar - Excelente pasta para soldar. El unico detalle es que se debe controlar muy bien la temperatura para evitar que se queme la pasta (queda como plastico una vez que se quema). Yo la emplee para soldar cables de cobre chapados en plata con soldadura libre plomo y me funciono muy bien.

### ⭐⭐⭐⭐⭐ Burns at 300c+ and is very sticky.
*by G***N on 4 August 2018*

This solder doesn't seam to like lead free solder. I tried to solder with lead free and this flux barley works when heated properly. It creates black tarnish and carbon flakes. Doesn't remove anything, and make a layer of goo in which the solder won't make a bond with the copper because it repels it like hydrophobic materials. And I can't solder to aluminum or other conductive metals either. The only thing it is good at is cleaning my iron.
