I heard great reviews on you tube about this product. Wrong way over priced I bought 2 for My husband and myself. over 400 dollars later we have been seriously ripped off. The taste of the tobacco is awful. and did not vape for no longer than about 4 cigarettes. Ordered e-fluid from china to refill but will not vape. we think the cartimizers are fried. We filled them and let them sit over nite. White Cloud will only replace the cartridges that are defective. I have to pay shipping. Wrong answer. I heard that the kr808d will fit their battery. we are new to vaping and are highly discouraged. We see other users of e-cigs get good vapor. We would appreciate any info from anyone .
