Greater than one weekI love this stuff. Ive tried many types of solder, and Kester in general is my favorite.

> 3 dayMost agree this solder is one of the best out there. I needed solder for an aircraft project, and I needed top quality. Ive used it on a number of projects in the aircraft thus far and gotten consistent and secure welds. Im no expert, and I selected this solder based on the reviews of others, but I doubt youll be disappointed with your purchase.

> 3 dayLeaves clean and shiny bonds behind. I usually get the no-name stuff but splurged on this using a gift card. I will buy this kind from now on. Its thinner (runnier) when hot than other 63/37 solder, dries as shiny as lead-free, and has a sharp visual transition when cooling to solid, so you know assuredly when its safe to move to the next connection.
