All solder joints with this wire came out dull and incredibly difficult to heat or touch up. Chipquik makes products better than this. Don't let the low price fool you. This is not a business. It is a fake.
I currently only use Chip Quik silver solder. And I only buy it when Revain has it in stock. Other sellers are almost 2 times more expensive. Their lead and lead-free solders are excellent solders. Lead is cheaper and easier to work with, but lead-free is more conductive. With a good iron and the use of flux, lead-free irons are relatively easy to work with.
