well I have been
vaping the KR8 for about half a year now... I love all the models I vape, but definitely find the cartos to be a necessary item to have.
they are a handy quick to go item,,, and performs pretty well.
They can be refilled if so desired... if you plan on refilling best to buy blank cartos and fill with juices you know you like....
Some people use this as their only
device and are satisfied with them...of course you will get your fanboys on any model, but from a consumers point of view it is definately worth the try to see if its your thing
like I said (this goes for if you know your fave juices) blanks/empties are the way to get the true experience with the KR8s so you know it isn't foul
juice that taints your experience.
Shop around and you will find great prices....
I can honestly say it is worth the try.... I don't live by them, but they also don't sit in a drawer collecting dust if you know what I mean (well some are since I have tons of blanks hehe)
