@Commander I bought my V4 from peptide critic, that's why I posted here.

@Nuncles I think that's priming, thanks for the description. I wasn't holding it up, so maybe that's why it seemed to leak so much.

I received a V4 pen today, my first. It wasn't as awesome as I hoped.

1. Is there a video about priming? I found videos about testing, filtering, and filling, but not really priming. I kinda figured it out by watching some other videos but would like to be sure.

2. I tested it with an insulin syringe that I already ran some water through and the stopper ends up being just above the line on the outside of the syringe. So it seems to be within .5-1 unit I lose. I did several more doses between 4-20 and eventually watched the syringe fill up and be about 2 units short of what it should be. I also tried to add just 2 units to another syringe to top off a dose I drew from the end of vial, but it only gave me 1 unit. Is this within the realm of normal?

3. I got the gluco-care tips (5 mm x 32 g) and they seem to leak a lot, is that normal? Leaking under the cap and out of the tip. Is there a trick?

4. It HURT! Granted, my husband kinda stabbed me, but I was suprised that it hurt more than the syringes I have with larger needles. My husband used it on himself first and didn't feel anything. I cleaned it, replaced the needle, and he did it on me. Yikes! Any tips?
