For a little Open Source Device the build quality an software are pretty good as well. Even the menu navigation with two buttons is pretty intuitive as well. Replacing the tip is a matter of loosening one screw.

Also having it automatically turn back to 150°C after a minute of not being moved and completely turning of after another few minutes gives you some peace of mind from forgetting to turn your iron of after usage. These features of course can be turned of if you where to want to...
