It was very nice to be cordless and portable solder if the tip doesn't work I can't desolder it either I'm very disappointed I used 18V 4Ah 72Wh I have a I pulled a cheap RadioShack iron out of a drawer many years ago after years of neglect and reached the tip still 150F+ on top, and no soldering or desoldering issues I am very dissatisfied with this purchase from Ryobi.
