I've had 5 of these for about a week now. 3 of them I filled with my favorite Dekang RY4 variant, the other 2 I filled with 2 of my VaporStation favorites, which I think have a small percentage of VG in them (they are marginally thicker liquids for sure). The Dekang liquid is 100% PG, so it is as thin as they come.
The 3 with the Dekang liquid are giving me no end of trouble, they taste burnt within 5-10 drags after a fresh filling, and I have to let them sit at least 30 seconds between pulls, or they taste burnt immediately. The other 2 I am abusing to no end, and unless I take 3 or 4 very good drags in less than 30 seconds, they are hanging in quite well.
I'm hitting these on my Buzz which is dialed in at 4.85v, and I'm really blown away at how good they taste. "Almost" as good as dripping on my regular Joye 510's at the same voltage. The only difference is they are slightly drier which is normal with most cartos, but I gotta say, from flavor and vapor volume perspective, they roast every other carto I've tried, and I think I've been through every brand and style in existence in the last year
I have 5 more coming in tomorrow I hope from another vendor, and I'm gonna try some of my other liquids, including one more 100% PG liquid that I use frequently. There is a possibility that the 3 bad behaving cartos have a defect, but right now I'm suspecting that they perform better with a slightly thicker liquid.
Anyone else notice this?
