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.
IMO 340€ for the whole set with the wirecutters and tweezers and such is still an ok deal, even though it is slightly expensive, because the accessories are probably good quality also, and there are few things as frustrating as bad wirecutters ;).
