Under $20 Soldering Irons – Are Any Of Them Usable

I’m testing some very cheap soldering irons from Amazon. The criteria were: listed as 60 watts or better and less than 20 dollars. And this list wasn’t even all of them. And I did learn from this that the wattage listed for the iron doesn't convey the heat it can produce at the iron tip.
