I have a question about irons. Currentky I'm using a cheap one from aliexpress with a digital screen and two buttons to select temperature. Does anyone have experience with that kind of irons and ifixit smart one?

The cheap one seems to have trouble for rework jobs or big job like soldering a component to a radiator. But while the ifixit does looks neat, I'm not sure if it's good enough to replace the one I have
