As an industrial and scientific user i highly recommend this solder for its excellent performance. As a result of using this product, I found that it created strong and secure bonds that have held up over time .Its diameter is perfect for smaller tasks and it activates quickly. The only downside is that it can be a bit pricier than some other solder options on the market. However, the quality and results make it worth the investment..
Pros
Excellent quality and reliable solder that is activated by rosin
Cons
Requires experience and skill to use correctly and may create harmful fumes if used improperly.
Perfect solder, melts well leaving nice and shiny solder joints. I've tried several other Chinese unnamed soldering coils before but won't be going back. Absolutely worth the price for this quality.
