I liked to use them because I didn't have a decent soldering iron. With these strips, I only needed to wrap them around whatever I wanted to solder together, then put a heat source near the strips. I could even use a lit match and they would melt right into the wiring. When they cooled, they were just as solid as a regularly soldered connection.
A while back I went into the local RS looking for the same product, and the people behind the counter looked at me like I was hallucinating. They told me that there had never been such a product and I must have imagined it.
Has anybody else ever used these? Do you know where I can get them?
