I just got my ego twist finally, i have held off getting one for a long time and finally decided it would look good with my new China DID. So i got it a few days ago and hooked it straight up to my vivi nova. The first time i fired it, it hit like a champ. The only problem it would not stop hitting. When i fire it, it flashes a couple times and then keeps on firing till it hits the 10sec cutoff. Everytime it does this and even if i unscrew the nova it doesn't stop. It is not genuine joyetech but by Hellosmoke. The only thing that it will work on normally is my 3.2ohm Bauway Cartomizers. Im thinking that this might have something to do with ohms because all my equipment is around 2ohm other than the bauways. It is just rather irritating because I love the way it looks with a vivi nova on top with a 5ml cone. I have some kanthal coming in so i will try making a higher ohm coil but i dont think it should make a difference. I have contacted the vendor but still no reply. Im not sure if this qualifies as DOA or defective since it works on some equipment but has very strange reactions to others. Just hoping to hear back from the vendor soon...
