So Saturday morning I got my syringe and tools out to load up some cartos. I only use them when not sitting around the house, so I usually concentrate the mess by filling several every week or two. I had planned modding some more and using more PG
juice to see how that worked out.
I had started with a pack of 5 XL 510 E2 R4 which all turned out to be semi-LR or 2.4-2.5Ω. The one that burned with vanilla flavor became an autopsy experiment and was destroyed. I had done the PTB mod on one and noted it was barely adequate (improved) using 50/50 fruit flavor
juice. I was able to do the PTB on the third one that I had already used. I also modded the remaining 2 new ones. I filled those 4 with either 100% PG or at least mostly PG, mixing in some 50/50 in the syringe for better flavor.
I managed to use one up between an hour or so while errand running Saturday and about a half day in the garage on Sunday. With the PTB mod and mostly or all PG juice these get the job done. They're performing at least as good as the eGo mega cartos, with a warmer less-airy draw. Based on my
vaping habits, I'd say that the one E2 I emptied out is probably pretty empty. It also dried out in a predictable, and not unpleasant fashion. That is, it didn't go burnt all of a sudden. I could tell it was getting a little dry and was able to get a couple more draws off of it without risk of gunking it up.
I also dropped a filled E2 in a small ziplock and kept it in my front pocket on Sunday while working in my garage. Both so I could have a spare on hand, but also check for leakage while wearing clothes I didn't mind fouling up while also being pretty active (rolling around under my 50 Ford pulling the transmission and clutch). No leaks. There wasn't even any liquid moisture in the baggie. Definitely will pass a business attire or briefcase use case.
Conclusion: Simply on the merit that they are less messy to store, I'll probably mod my remaining 5 E2s and put them to work in favor of my eGo mega cartos. By the time I tear these 10 up, hopefully enough of the better functioning 3Ω R4s will be out in circulation for my next order. So call this a cautious 2 thumbs up.
