Got my replacement Pax this weekend and noticed 2 differences vs. my first one.
This new one seems to heat up a lot quicker than my first, I never actually timed my first one but this one is noticeably faster at getting hot and turning green.
Also the draw on this one is MUCH better than my first, this one feels like I am hitting a nice loose joint, which is perfect IMO (verses my first one which felt like I was sucking a thick milkshake through a straw)
So glad to have the Pax back, I missed it so much the 2 weeks it was away.
Please post your heat-up times.
If there is an improved draw then the screen must be different, since that is the most limiting part of the the path. Is the edge of the screen noticeably wavy or have notches? Does it sit differently? Is it now perforated?
