I recently switched over from the Zelos Mod kit to a Smok TFV8 Baby. 3 ml tank, can have a good restricted DL or fully open big cloud. It's a low wattage sub ohm setup. Kit comes with 2-3 different coils. My sweet spot with Smok .4 ohm coil is 38 watts. So not maxing out the Zelos and it fits perfect to the mod. Good switch from MTL to this tank. Good taste and cloud production. If it was in stock at any of my local vape shops I would get a Smok Spiral which is there designed flavor tank. It's even more of a lower wattage sub ohm tank
