Bought a kangertech subox mini 50W online and I checked the authenticity and sadly its fake. Bought it on Ebay from a Top Rated Seller and the product had 209 buys. Mostly good reviews. He only had 5 bad reviews and 2 of them said theirs was fake too. Should I try to vape on it? Is it safe? What should I do if I don't want to return it?
