The very definition of semi-professional.
I am a musician and hobbyist who makes his own leads, builds his own circuits, repairs his own gear. I use one of these things to do what I need to do, and it does it passably well. The sponge pad comes adrift far too easily, the tips are not the best; but compared to most DIY store soldering irons it is head-and-shoulders above them.
If you want to spend three figures on professional gear, go ahead. If you want to spend £10 on a rubbish soldering iron, go ahead. This is perfect for the limited-budget hobbyist, or the self-maintaning musician. It's not perfect, but it is the best in its class.
(Incidentally, Maplin sell this same item for more money. Why would you?)
