I've bought 2 batches of V4L's new premium blank cartomizers & have noticed a definite difference between the 2 & the original blanks. Of the 2 batches of premium blanks 1 set (hard caps) seems to work well & can be refilled @ least once or twice. The newer ones with the rubber mouthpiece plug seem to work OK the 1st time you fill them, but can't be properly refilled at all after that or other wise you either get a burned taste or they constantly spit juice in your mouth. As compared to the original blanks (which appear to have been discontinued by V4L about 1 week after the premium blanks came out) which I could refill 3-4 times with very little change in flavor or vapor production.
Has anyone else noticed this & if so are there any other KR808 blank cartos that someone would suggest?
