Just received some 510 cartomizers from Litecig. If these things have a decent lifespan and hold juice for half as long as a KR808 carto, I am sold! The vapor and throat hit is equal to a regular 510 atty and much better than the KR808. I would suspect that it is also going through juice much faster than a KR808, but so far a partially filled carto has outlasted any 510 cart config I have tried.
My primary reason for posting, though is to warn against filling by removing the mouthpiece plug. I ruined one by doing so, and as you can see in the following picture, the construction is different than the KR808 carto and does not lend itself to removing the mouthpiece. The tube going up through the middle appears to connect to the mouthpiece. I filled another one with a syringe and it worked, but I may try the condom fill method as well.
