This thing sucks! It's meant to! I had to replace a memory chip on my Atari 130XE. I've never used a tool like this before, but it worked well, and didn't harm the pads at all. I set it to 350C, and it melted the solder each time, and sucked it all up. I had to use very minimal force to pull the chip out after it cooled down. Well worth the price for home & professional repair!
