Pen button feel - GOOD. the buttons on these pens have a nicer "crisper" clicking action than the buttons of the PW517 which feel a bit soft/mushy in comparison
Pen IAF - GOOD. Huion says 2gf for these pens. Seems accurate. A little more sensitive than the PW517 pen which is at about 3gf.
Pen maximum pressure -
VERY GOOD.
Huion states 500gf. I saw some variance a little bit of variance - not much. Overall the PW600 pens are very consistent.
