I was hoping someone could possibly give me some ideas on a GOOD new mod to go with my Uwell D1 tank. I bought 2 smok alien 220s about 2 months ago. One of them fried about 4 weeks later. Then the second one just quit firing yesterday. I'm very discouraged now on what to buy that will be good. I had always though smok was such a great brand. Any ideas would be greatly appreciated!
