In my OPINION I personally hated this item. I had to use it for about 20 minutes and at that 20minutes the tips started to ruin by chipping and bieng coroded by the little solder i used. I even had a sponge yes to wipe off the solder. But still i ran through all 3 tips in about 3 hours of use at different times. So please dont wast your money on this cheap soldering iron. But if you insist on saving a few bucks be my guest, but don't be surprised when your ready to throw it into the trash.
