I am no fan of desoldering, so when i saw this tool on ebay i was skeptical that it would perform any good. So i gave it a whirl today to see if it was going back or staying. Well its staying, its actually pretty damn good. Its not cheep for Chinese crap but it does the job. Nozzle over a pin, wait a second or 2 for the solder to melt, hit the button and suck it out.
