Works well
I have a few hobbies that occasionally need to do soldering for. This works well and I was happy with the performance. I think it worked better than the cheap stuff I had before. This thickness was also easier to work with for a circuit board I soldered components to.

Thing’s just not what it use to be
Buying this for the exact chemical composition was a mistake. Sure I need to replace an old stocked product which I’d used entirely. Additionally the old Kester was perfect. There’s so much resin in this that it’s caused some of my batteries to overheat. For $20 at Harbor Freight you’ll be just as satisfied; if not more.

Its worth a little extra $ for the better stuff (like this Kester 44)
I'm retired now but I was the 'go to' guy for SMD and all other sorts of soldering at several major companies. I tried the 'west of the pacific' solder and they were just not worth bothering with. I did have some successes. But I also had some abject failures. Now I think for something I do so rarely now I'll just stick with Kester since I have faith and experience with them and I just don't want to mess up some more expensive stuff with saving a buck.

Among the best for many decades
This was the best in the 1960's. It is still excellent.
