i bought pretty much every item they have. i have 5 of their cigar. been through two so far. they arent bad at all so far, fairly stable but the paper used to cover them is cheap. they use 3 batteries as opposed to 1 in the loong/ruyan model. also some of them leaked as the foil cap was not properly secured on all of the cartridges. i got the cigar tube too which i really like. the liquid is of the type that you can inhale and exhale. i got one extra-high flue cured. you get a hit off of that for sure.
Didn't see htis comment before- this is exactly what I'm experiencing with hte cigar so far- one of my cartridges leaked, and doesn't seem ot be producing much in way of vapor which I suspect is due to hte leakage and beign a bit dry- but what juice hteir is in the Marlboro flavor is very good- much different than the Ruyan flavor, and I'm not sure which I liek better- I'm quite liking hte Marlboro flavor alot actually. The build of hte cigar's paper as you said, isn't as good as hte Ruyan to be sure, but it's 'o.k'- The only thing, is hte flavor is a bit light- it could be a better hit flavor-wise and nic-wise- At first hte nic was great- very nice hit- better infact than the Ruyan, but it's driopped off a bit whereas the Ruyan hit remained for quite some days during my test- Not sure what the issue is with hte cigar I got, I've noticed the atomizer bridge is a bit crooked, but htis shouldn't affect hte nic and flavor hit- will have to mess with hte cigar a bit more later tonight as it's now nap time

Will start my review tonight.
Added- this cigar is creating quite a wallop of vapor- I took cartridge off, straightened the atomizer, and repositions the atomizer on the bridge, twisted it slightly, and it's now vaporing liek crazy- will see how long this lasts, oh, and hte taste is coming htrough better now, a bit stronger, quite nice actually- I think htough on this particular cartridge, that I have to drill a bit bigger hole in the end as the draw is a bit hard, not big enough to pull enough air through- We'll see hweat happens later
