The vaporfi pro starter kit is a rebranded kanger evod sold at $50, more than 3 times the price of buying authentic anywhere else. The vaporfi rocket set sells for $120 and is a rebranded kanger emow, once again triple the price. The vaporfi rebel looks like a vamo and nautilus combo for $180, and the vamo is being discontinued in lots of online stores. The vaporfi vox 2 is a 50 watt box mod for $170, and I can't find any information on the chip, but that's literally about 4 times more expensive than comparable box mods. They sell a rebranded 18650 battery that says 35a and 2500MAh. Physically impossible and 3 times the price of a Samsung 25r. Their volt hybrid tank is $60 and is a rebranded kanger subtank mini, double the price at a decent retailer.
So, all that being said, they apparently have good customer service. At those prices, that's ALL they have. If you want quality, buy an sx mini m class (for TC MODS) or a provari (low wattage). Maybe even buy a dna 200 device when they come out, or buy a snow wolf 200 now. You'll get better stuff.... maybe it won't have green o rings, but it'll be better.
