Strangest thing is, you being angry with me, for your own words, claims, statements, failures, and ignorance.
And, no, I see nothing "inferior" about the ~$1.00 50W ceramic heaters, or whether they are made by "THE GREAT GOD OF CHINESE JUNK", or "THE GREAT HAKKO GOD."
50W is 50W ... and as I have pointed out, if someone supplies me with a unit, heater and tip made by THE GREAT HAKKO GOD, and I solder a board, or I use my equipment made by "THE GREAT GOD OF CHINESE JUNK", you, or no one, would ever know the difference -- despite the claims which might be made by the terminally insane.
Indeed, using only common sense, and choosing HEAVY tips, 900M-T-1.6D, at a cost of 0.64 each, when purchased in single quantities, I see no difference in the actual performance of the unit made by the hakko god vs. the cheap chinese god.
... and I don't need to measure it ... I believe my eyes and senses ... you simply need to make sure you have the RIGHT cheap element for your CHEAP stations ...
Here is such a tip, since the tip is the single most important component:
