i started vaping with an Elief 30 it broke down (510 pin got stuck and wouldn't fire the tank) in the first two weeks. I call them and they said it was a known issue and asked me to take it back to the store for warranty. i did but the store had a two day return policy and would not help me. so i called them back and they said they would also not help me. I would agree with others on here and say that you should get something a bit more quality. I went from that 30 to an IPV D2 and i love it. i have dropped it (even in the toiler once) and it looks like crap now... but it still works. spend some more $$$ and get something that will last. IPV, Innokin, SMOK, Wismec, sigili and tesla all have good options out there. Try a site like fasttech for good deals if you can wait. Go to your local store and sit down with the vape specialist and they more than likely set you up with a good mod.
I remember a little Bear recommended several mods and the IPV D2 was at the top of the list.
