Purchased from vapordna. At a glance, the mod looks great. Excellent feel and texture. Feels incredibly rugged to the hands and lightweight especially. The only buttons are notably just the firing buttons itself. Unique thing about this mod is the descending and ascending watt change can be found inside the plate doors where the battery is located. Changes watts quite fast and you can change the volts you like it to fire at as well or ampage. The tank or rda where it's inserted sits fully flush for 22mm. Everything about it was perfect. Even more interesting, the batteries that are located to place in the back glow in the dark.
However... This mod really spooked me. It has a very loud buzz. Probably as loud as a florescent light or bud zapper light being buzzed. This did not sit well with me. I called them up and the nature of this mod was "normal". I did not second guess myself and unfortunately returned this mod. It was just too much for me to bear that sound vs the light "ping" sound of the sigelei. More importantly...
This mod has a one full second and a half delay upon firing. This mod had so much potential at a glance, but unfortunately went down hill having those simple cons not wanting it anymore. No TC was included in this chip & to confirm it is not any SX or DNA chip.
