Most interesting to me is that they put the display on the soldering station/battery pack thingy instead of the iron itself.
I bought my soldering station with air solderer and iron solderer for about 40$ from AliExpress, the ones with IR bottom heater cost around 90-100$
What's the IR bottom heater for?
IR bottom heaters are usually not strong enough for reballing. They're for boards that are hard to solder, because there's a lot of copper or a heatsink for example.
The bottom heater preheats the whole board, not to soldering temperatures but enough to make soldering a lot easier.
