It's hard to place exactly at its price point. At the full kit price it's approaching the cost of a mid-range Hakko soldering station which you can use all day every day.
I see this is a potential "better quality" portable option for a professional (than something like a Pinecil and a TS100), that might want to carry it around or use it when not at a desk, but the quality and performance remains to be seen (though I do trust iFixit).
At £240 in the UK, it's about 2.5x the cost of the Pinecil + Powerbank (which I already had). If I didn't have a Hakko soldering station and wanted something portable but capable to use fairly regularly, this seems like a good option.
For everyone else, if you already own a PD powerbank, the ~£25-30 (~£50 with a bunch of tips) for a Pinecil is _much_ more palatable.
