I also did order the PCC? Personal Charging Case: going to post office to pick it up today i'll let you know if it helps.
I love my PCC! I believe it needs to be kept upright also, though. I noticed a couple times, when I took out the atomizer from its little well, that it had some
juice residue on it. Seems it may have gotten in there from the cartridges, even though I have the little plastic covers on the cartridges.
Actually, I just figured it out as I'm typing this. I know where the liquid residue came from. If you drip on your atomizer, and you store it in the well with the open side down, that's where it came from. Unfortunately, if you store it with the open side up, it can be difficult to get out, since the edges of the open end will be flush with the opening of the well.
Since I carry a purse, I don't have the problem you guys have, of where and how to carry your e-cig. I have a clear plastic tube (from beads I think) and it sits vertical in my purse, and my 510 fits perfectly in there and stays in place. Then I also carry the PCC with the spares.
