Hi guys think i've solved the penny leaking.
If you look at the photo you will see the comparison , the one on the left i got some fine wet & dry paper and lay it on an hard flat surface and went round in circular motion .
Since having the penny i've always had flooding issues , I think even with the mouth piece all the way down the liquid was seeping through the gaps in the ring.
I've had the very same issue....more of an issue lately on my Ody v2 for no other reason that I've been using it quite a bit more than the Pene. I just make sure the ring is tightened down before I refill as the ring sometimes works loose with constant use of the liquid control. Leaks through the center post no longer an issue and both tanks work as intended.....very, very well. I use mostly 70-30 pg/vg.
