I did more or less the same Thing, i bought a Luxe X Pro, liked it that much i bought a 2nd, Bought a Gotek Pro, was enjoying it till i put a New Pod in it which kept giving me Dry Hits, Binned it because it annoyed me. Gave a Luxe X Pro to a friend to help her stop smoking. She Loved it and hasn't smoked since, she also bought a 2nd as did i to replace the one i gave her. I then bought a SX Mini Puremax. Also been buying Salts like you but not as many. I think i have 6 Boxes, i mainly buy 50/50 Liquid and have boatloads of the Stuff. The friend i gave the Luxe X Pro to visited me again Yesterday and whilst here ordered a Puremax Herself. She loves vaping now
