Not only is this thing a joke but its actually really dangerous.
Lets just say you have just built a 0.2 ohm coil (lowest res it can go) and you start vaping it at 180W. Assuming you are using pure VG juice, PG isnt viable to use at high wattage. The VG will react to the insane amount of heat produced by 180W causing it to reach near flash point, at this stage it can turn to a chemical known as Acrolein. Acrolein is an extremely toxic and carcinogenic chemical made from broken down glycerol (VG). In low doses it can cause severe airway irritability, this "box god" would create Acrolein at a level beyond human tolerance.
Before any idiot tries to say "Well mechs can produce over 180W why havnt we heard cases of people getting sick off a mech". Mechanical mods can definitely fire at wattages similar to this device. However Mechanical mods have the ability to run at a much lower resistance (0.09-0.07) therefore a lower gauge wire can be used covering more surface area and having a much longer ramp-up time therefore avoiding heating your juice instantly to a heat close to flash point. To achieve the lowest resistance that this device can go (0.2ohms) while running 180W would have a coil with a mere fraction of the surface area of that if you were to run it on a mechanical mod. Also vaping at such a wattage at a higher resistance coil compared to a mech would mean you would be running a voltage far too high, more voltage across the same amount of surface area produces far more heat. Keep in mind that the absoulte max voltage a mech will fire under low res would be approx 3.7-4.0v where as this mod will happily pump out 6v to the coil.
After reading this I hope it has shed a bit of light on how silly and dangerous this device is. But if your using a lower wattage you should be fine, but then that is a bit of a waste buying a 180W device and not using 180W.
All in all if I could be as blunt as possible, you would be a complete (MODERATED) if you were even considering using 180w on this mod after reading this.
that's like saying those 400+ watt fog machines create acrolien and kill people at concerts.
it's all about wire gauge, not just ohms.
