Review: Perfect for Stainless Steel. - Had a Stanley cup which the handle broke off. Stanley replaced the cup but didn’t have the same color so figured I would try to fix the old one. Epoxy wouldn’t hold so thought about soldering it on. After some research found I needed a specific solder to do the job. This worked perfectly and the handle has be securely reattached.

### ⭐⭐⭐⭐⭐ This solder works well with stainless steel as advertised
*by C***D on December 7, 2024*

The application was to replace a pair NiMh batteries in a Water Pik powered toothbrush that was never designed for the owner to replace. The replacement batteries used Stainless Steel terminals which need to be soldered to the internal wires. This was the perfect size for a small job and reasonably priced. The solder’s built-in flux avoids having to buy a large bottle of liquid flux avoiding additional costs.
