They do have the best inventory of vaping needs in my opinion, from flavors to mods and atties and such.  The place is quite large compared to most vape stores that I've been to.  I'm just not too fond of their customer service.  The lady who was helping my gf and I was pretty nice but the other two guys who were there were not as nice; I felt a little attitude when I was talking to them for a little bit.  I come to vegas frequently, and I'll probably come back next time, only because they have all the goods.  Hopefully their service will be better next time I'm there.
