Review on Uxcell 900M T Rework Station Soldering by James Eledge

The former oxidizes much faster than we would like (even at the price), but the latter holds up better. They're cheap so don't expect much, but the tip is decent. Just don't overheat the iron (you'll need to keep an eye on the temperature for fine work anyway) and clean the tip often and they'll last a long time.
