Nice nut I think it's just more hype with all the CZ, TZ, MZ, TP - BS He provides no data as these feature even having an effect on a print. He should at least show photos of the difference. If changing these features have an affect on different types of filament that would be useful. You could set one up for each type of filament you use - but again no data. No video explaining it, just pictures and a LOT of reading (I hate reading)
Right now it just looks like a gimmick.
Some things are meant to be closed. Your mind isn't one of them.
