Hmm.. so many positive reviews of this.
My $.02, I've been coiling for.. a few years. I've tried a LOT of tanks and RDA's.
There is almost NO easier to coil deck, than the Velocity. Especially for dual coils. VERY friendly. I personally find this a lil tight in width for a 2 post dual for wicking, IF using spaced TC wire and you want something above .3 ohms. For contact Kanthal, no problem.
It is a very unique design. It will leak IF you set it on its side.
My issue is flavor. I've tried a few different builds, and it isn't doing it for me.. To be frank, if you want NO leaking problems, awesome flavor, and not messing around with building coils and wicking, I can't speak highly enough of the Uwell Crown tank with .25 ohm Stainless Steel coils. Used in temp control mode, a $2 OCC coil is lasting me over 2 months apiece, but it isn't my sole device. And with alcohol and a Q-tip, you can get longer. NO leaking, TOP fill!, NO funky drip tip with spit guard, NO weird nipple built in on top for the tip.. Yeah, for the money, I'm going with, and recommending to a noobie, the Uwell Crown ANY day. Sorry Aromamizer fans, if you haven't tried the Uwell Crown or TFV4 tanks with OCC coils, maybe you don't know what you are missing in a flavorful tank system? Just my experienced opinion...
