I wish I knew this tool existed years ago! I used to get so annoyed using small blowtorches to shrink and crimp ferrules. Every time you finally got that stupid thing, the wind would blow it away. Not with this amazing tool. I love it! I bought it to remove the screen from my Microsoft Surface to replace the SSD. The ability to change the heat settings was vital to getting the job done, as was the choice of attachments. Other heat guns only have 2 temperatures, but this thing is versatile. Next to my 4 pound hammer, this is my favorite tool. Also works great in the cold, the bolts also stick.
