works great, great conductivity

works fine

It has stood the test of time. Flows great and makes a good connection that is strong.

Best solder

Works great for small pcbs

I am used to Alphametals made in Brazil. The trade mark is BEST and it is really the best. This one from Kester is not good at all. The flux core is not continuous, so when you stat soldering, some spots go fine and some dont. I need to use extra SMD flux paste to finish the job, what takes longer and compromises the quality. I would say do not buy, but these company took over the market and that is the only option we have. The other option is to import from BEST in Brazil.

As advertised, great solder!

Good size for fine through-hole work. Flux gives perfect wetting and doesnt smell terrible.

This is what you need for SMD work, from the company whose name means solder.

better off buying another brand
