I bought 3 different rolls of Chinese Lot and all 3 were terrible. I will never skimp on solder again. The cost of 3 is roughly the same as the cost of 1 roll of Kester. In the future I will buy Kester brand solder every time I need solder for my hobby. There is no comparison in solder joint quality with Kester which is vastly superior in quality, strength, fusibility and distribution.
