There are two types of tanks, the carto tank and wick tank, I suggest trying both to see what suits you best. I actually like both types. I use glass tanks with cartos and the flavor is fabulous. I also just tried the SMOKteck Screw Tank, MyVaporStore, new name is Titan tank, Got Vapes, it uses wicks. It has preformed very well, with wick tanks you have to watch how full you fill your juice to and also be careful to not use higher volts if you use a LR one or it will get fried, other than that this wick tank is consistent with great flavor. Fill in am and vape all day no fiddling. bnrk
