I have recently purchased a VIP ECIGARETTE, its the best thing I have ever done. However, is there a certain type of eliquid I can use to refill the cartomisers? I bought some eliquid from simplyeliquid.com and it has an electrical burning taste. On the VIP website it says their cartomisers are not compatible with eliquid. I have done some research and think i may need to buy a VG based liquid. Any help would be much appreciated.
