So, does it make any sense to anyone here that the Davide would have a break in period? I just got two more to bring me to a total of four. When I got my second one I had problems with dry hits when I first got it, that went away after a couple of dissembling/cleaning/reassembling rounds. I figured it was a random quirk. Now I'm having the same issue with the new ones.
When they arrived I took out the adapter ring for dual coil use, cleaned them, put single coils in (from the same batch I'm using in my others), and started using them. Dry hit city. So I used them very carefully until refill time, went through the cleaning routine, and now one is fine but the other one is still having problems.
This makes no sense. They are very simple devices, with the air feed coming in a small hole in the 510 connector and two slots across the base to get the air to that. The only possibility I can see is that, while staring at the air flow hole there is what might be a tiny bit of silicone or something at the top edge of the 510 threads. I thought at first it might even be yet another of Anyvape's dreaded itty bitty o-rings, but it is not.
Any idea from those of a mechanical bent on why this would happen? Especially on such a simple, non-adjustable item? Especially when it goes away after some use? The only thing I can think of is that for some reason the o-rings need to compress a little, but I do try not to squish (technical term) things together too hard.
