I just sent some pen styles and 6 filled carts home with a friend who is interested in vaping. If she wants to buy her own I want to know where to send her. I want to recommend the KGO because I know she cant afford the extra cost of batteries and a charger right now for an E Power. I have APVs so I dont know anything about buying a KGO but have read that some vendors are selling earlier versoins from before the bugs were all worked out. Any good advice? Thanks in advance
