This one is under $16, and from the picture, appears to have a 2mm air flow hole. Here's the link.

Ok received this one today, it does NOT have a 2mm air flow, it has the same 1.5mm air flow as my $17.xx version, I know this because a 2mm screwdriver will not fit in the hole but a 1.5mm screwdriver fits like a glove.
The o rings are red, NO spare parts, came with a wad of what looks like "cotton", 2 pre made coils that will not fit under the screws, the gauge wire is too thick, and the classic blue screwdriver.
Had NO o ring for the chimney and the top cap where it threads on, so I used a drip tip o ring there. Had NO wick ring thingy either (don't think that makes any difference honestly? )
I could not take the threading (510) piece out to remove the positive pin assembly, I tried but it sure didn't feel like it wanted to come loose. I'm sure it comes apart but I needed more time and the right tools, which I did not have at that moment.
The plastic
tank just barely seals against the upper and lower red orings. Very loose fit, in fact I can spin just the
tank once it's filled, assembled and attached.
It is wobbly even cranked down as far as I can safely torque it down on my wizard, I think that has to do with the 510 threaded part where the positive pin goes. I may have loosened it trying to separate it? Not sure until I examine that further.
It is MUCH quieter than my other erlkonigin, a lot less air noise (wooshing). It did come with a metal drip tip and adapter.
The 510 screw in the base is basically flush, but even flush it makes contact and fires. But still wobbles. Maybe this one had a longer 510 connector? Or maybe trying to disassemble it I moved it down?
Best part of the new one is less air noise, same draw with no afc. [emoji6]
