### ⭐⭐⭐⭐⭐ Made in china
*by D***L on January 24, 2026*

Worked well for soldering a new battery into my key fob but wish I knew this was made in China. I'm always skeptical of Chinese made goods but hopefully this doesn't have lead in it

### ⭐⭐⭐⭐⭐ Lots of solder wire, good quality
*by A***R on December 3, 2025*

Good solder for electronics projects. With this much on a roll, it lasts a long time.

### ⭐⭐⭐⭐ Solder received looks different but seems to solder okay.
*by E***I on July 23, 2025*

The 50g, 0.8 dia. spool of solder I received looks different than the advertisement picture on Amazon. Spool I received doesn't explicitly state lead free on the label as advertised, however, the label has RoHS printed on it which should indicate the solder to be lead free. It seems to solder fine and easy to melt and flows okay, but I think the additional use of rosin might help the solder flow better.
