been avoiding em for a long time since i've heard allot of bad things but finally broke down n got some from madvapes. i decided to go with metal ones so i wouldn't have to deal with any leaks or my menthol juice cracking em, got 2.5 ish ohms, xl. i do like these things allot but like i thaught they have some wicking issues, when they work they're great though, a little more mellow then my dual coils but still a decent throat hit and great ammount of vapor n flavor. any tips on how to make these things wick better would be appreciated, only thing i can really find is for the clear ones since it's easier to get the tubes off, dont really wanna go threw the hastle to get em off unless i have to but if thats what needs to be done then i guess i will
