I am a complete amateur.
Before, I had the kit that came with the soldering iron.
Compared to that, this one solders immediately, cleanly, and at a lower temperature. I put a little solder and my work turns out perfectly.
However, be careful not to inhale the fumes; if you don't want to wear a mask, do what I do and put a fan on one side. If you read the front, it says a bunch of problems that can occur if you inhale the fumes often. So be cautious.
Happy shopping.

It makes very clean solder joints and does not require extra soldering. It melts at a fairly low temperature. A worthy replacement for my old weller wire that ran out. Lastly, it smells a bit strange, so you should wear a mask and protective equipment to avoid any issues.
