Can someone give me the TLDR on pens

Where did you get yours from? A lot of stores seem out of stock.

Suprisingly, Ebay came through for me. You can get them there now!!

Pretty much the same process. Although I've found it easier to vent with an insulin syringe and take the removed plunger to exhaust air by pushing up the bottom of the cartridge until it's within 5-ish units. If I try to remove the larger portion of air by clicks I can't seem to get the air bubble out.

I got one of those cute cart holders with the cylinder in the middle for pushing the cart plugs in from allthingspeptides
