Hi. Please allow me to say that I am an absolute novice and I have almost no knowledge with regards to vaping. Having said that, I am currently using a Smok Nord4, and a geek vape legend 2. I simply LOVE both of my devices, but the store from where I purchased my devices is behaving very deceptively to me, to say the least. Thus far, they have milked me of quite a sum of money, with lame excuses that my devices do not necessarily come with warranties etc. Please advise me, although I just want to cut a long story short and deal with vape stores that are not there simply to make money. I really appreciate your kind advice and assistance. Regards. Abdool Essa. North Beach. Durban.
