upon receipt of the unit I wanted to return it because it seems to me not powerful enough for desoldering electronic components (so I'll use it instead to weld) Finally, given the correct price to less than 18 (note the price when you say it does not seem you expensive because they often change at the site, and as a result we do not know the correct original price says "cheap ":)) I keep it because I have a bigger brand Aoyue 852 ++ a wind tunnel that allows desoldering higher temperature reached more quickly
