I'm sitting here vaping with my 19mm Pro-V, and staring at my beautiful new 22mm Pro-V2 which arrived today. I'd love to be able to use the new one but unfortunately I am unable to get it apart to use it. Short of mangling it with a small screwdriver, I'm at a loss. I remember having this issue with the other one--- not sure how I did it. Thank goodness I ordered the softer o-rings to replace the existing. Now, if I could just get it apart.......any suggestions? Edit: thumbnail, no go.
