I've purchased this one and very much happy with it
A bit confused with the atomizer cleaning but found ways of cleaning it, OXIACTION does the job for me
Their customer service is not the best, they claim to answer your emails in 2 hours but thats as long as youve not purchased the product, one you have it and need support it takes up to 2 days
The case is pretty nice, contains 2 high , 2 med and 2 low nicotine cartidges which is not equivalent of 6 cigis, I'd say 2 or 3 cigarettes.
It also comes with car charges and free 10 extra cartridges which is nice. They might ask you if you prefer the USB charger insead of car, dont choose USB if you've got a Nokia mobile, coz the USB charger is Nokia PC cable which goes trough a socket in the charger
Hope it helps
