I'm just throwing this out there... There have been a lot of complaints lately about carts and smileomizers dying prematurely. I have personally given up on the smileomizers until the issue can be resolved, and switched rigs all together to an I taste VV and a kanger v3 mini tank. I bought a 5 pack of atomizers and not 1 lasted past a day. Either burned up the coil or burnt taste. So I went back to a carto tank with smoke tek cartos. My initial thought was the kanger atomizers were junk. I have not had good luck in the past with bottom coils. So I went back to what I know. Problem is I've almost gone through the 5 pack of smoke tek carts already. The only common link is the V4L 18mg peach juice that I use as my all day everyday juice. I would like to hear from anyone else who changed from V4L cartos to other manufacturers and are still having similar issues.... The dying coils premature clogging etc..
