Review: Excellent solder for most electronic repair or builds. - This solder is easy to work with and is high quality. The solder you get with soldering irons or with other solding tools at the home improvement locations usually isn't as good as this. Most of my projects are electronic related. This wire is excellent, has a good working temperature and holds up well. Most of the other stuff I have is way too thick and requires a much higher tip temperature, something I don't want, for the jobs I do this solder is well suited.

### ⭐⭐⭐⭐⭐ Great solder, no complaints.
*by J***R on June 19, 2026*

Purchased this one to replace my last roll which I recently used up. This is great general purpose solder - the flux flows well and doesn't smell too rancid, the solder wets out to leads and PCBs as expected. Maybe not the best for super precise work, or where you can't use leaded solder for whatever reason, but for a hobbyist or tinkerer this stuff really does the trick.
