### ⭐⭐⭐⭐⭐ Works great, no issues
*by M***D on December 8, 2024*

If you are concerned about lead, this is the ticket. The melting characteristics are very similar to standard tin/lead solder. Personally, being a chemist, I know that lead does not vaporize at soldering temperatures, so lead exposure is not much of a concern. But there may be other reasons to avoid lead so this solder is an excellent alternative.
