Well, I received my CE2 510 cartomizers today, was shipped July 29th.
I am sorry to say that of the 60(12 packs) I ordered that 3 were of the 7 hole revision, and the rest were the 3 hole revision.
All the cartomizers have the narrow slots/cuts for the coil/wick in the cup(checked one cartomizer from each pack)
So far I have experienced the bad taste on initial use, and the dry coil metallic taste after around 3 drags on each type.
Thanks to those that received these revisions earlier that provided
ideas/workarounds I was able to to get these cartomizers to work very well.
Did a 20 min soak in vinegar after removing the outer and inner caps, and then a 20 min soak in boiled water. Rinsed, shook out the water and dry burned till coil went red. This fixed the bad taste issue - verified by the wife, used the juice from the same bottle for the initial fill and the fill after cleaning.
Used a precision screwdriver to gently open up the slots to relieve the pressure on the wick and replaced the inner cap with the cap from a 510 soft top cartomizer(Boge) to act as a O-ring and a T-Tip instead of the end cap. This seems to have fixed the wicking problem and can vape away without problems.
All in all I am pleased with the cartomizers performance after tweaking, and I do understand that these issues are supposed to be being worked on by the manufacturer, but I am disappointed that I seem to have received the older revisions since I cannot forward samples to fellow Canadian vapers to try straight from the package.
I am not sure if this is the case but I think It may be that I am from Canada and not the the US and had some of the older stock sent
.
I will order again later on once the product has matured since when I get them working right they are better than my old cartomizers in taste and vapor production.
All the best, Happy Vaping,
Wing.
