This iron heats up fast and holds its temperature well as you use it. It was easy to use. Only two improvements that could be made:1) You set the temperature in fahrenheit, and then the display shows it to you in Celsius. Kind of awkward, but a known "feature" as there is a fahrenheit/celsius converter in the instructions. It's especially awkward if the iron is hot when you adjust, as the reading will then need to "tick" down 1-by-1 from the fahrenheit temperature to the celsius temperature (i.e. it will tick from 200 F to 93 C), which will take 10ish seconds.2) It's big enough for this board, but for my ultrawide board, it is slightly too narrow to get the wax melted in 3 passes. So, I either need to do 4 passes, or do the center pass in "drift" mode sideways. I think an extra half inch of width would be enough (that's what she said).
