Solder new. Did the job I bought it for. As indicated on the packaging, the iron may smoke a little when heated for the first time. Smoked for 5-10 minutes then quit. There were issues with the "tinning" of the tip, but I'm sure it was my fault. The iron is very light and fits comfortably in the hand. Very comfortable grip. I was impressed that the handle itself didn't get hot. It would be nice if some sort of wire holder was included to keep it off the countertop, but no.
