That's just a few days but i like it. I submitted a review.I had not great expectations. We should know it's only pc, inexpensive mod...not a Lost Vape or home made high-end mods. It looks nice, it's very lightweight. I don't like too heavy mods, only my Hcigar vt 75D is a little heavier than my other devices. So as for now i'm very satisfied, i have only three 2 × 18650 mods - Hcigar vt 75D, Tesla Wye 200w and my new Wismec Sinuous v200 and that's the end, just now i don't need more of them. it's only a ca 30 usd and i think that it was a good choice.
