I have a Defender from VaporNine.com. From what I can tell it is exactly the same as the Riva 901 sold at liberty-flights.com. I saw some reviews of the ego-t system and am wondering if there is any adapter that would let me use the ego-t atomizer on my Defender battery. I kind of doubt it since with the ego-t the cone and atomizer are one piece, but I thought someone here might know. Thanks for your help!
