Great set. Worked great for soldering a worn joint in my pressure furnace range. I was watching a YouTube video showing solder joints failing or wearing out in my brand of high pressure furnace. I lost all ability to light the stove and was ready to throw it away. So I decided to order this kit and give it a try. I soldered the exact connections in the video and then closed the oven door and turned it on to 450F and it came up to temp within 5 minutes. I was very pleased. As this is my first work and kit purchase I have nothing to compare but everything seems to be of good quality. I can't hesitate to give it 5 stars. The wire seems flimsy, but that suited me.
