Review: Great value - I wanted some decent solder that would actually flow and melt at the temps I use and I can say this solder exceeded expectations. This melts extremely well and has good flow into joints and doesnt leave a dry joint. Great product.
Review: Good solder, great price. - I am using this for electronics repair. First use left me impressed with the good quality of this The melting point is good, the flow is good and the adherence is good. I have not done any mechanical testing on joints but I expect it is fine. I used it to repair a broken game cartridge last night and it worked. This solder did not seem to melt or flow at a noticeably different rate from what Nintendo originally used.
