This iron didn't deform like I expected from UT. There's no temperature control, so if that's what you're looking for, this isn't for you. If you're working on small PCB projects, this is fine. But if you work with a game console, computer circuit board or something small, this iron will not work. If you're working on boards for a drone, power bank or similar, you'll be fine. You must have it plugged in or it won't work at all.
