Its about the coil right ???Yeah, didn't have the patience for fasttech. E-Wolk had a reasonable deal that included five extra Notch coils. And I heard there's some issues with the accuracy of the temperature control on the Notch coils because of the Nickel leads. Temperature Protection seems to kick in fine though, so I'm satisfied too.
I've been using the delrin drip tip included with the Cuboid Mini and haven't had any issues since. This style of drip tip does restrict the airflow though, which is a shame. I agree that this amount of spitback is not acceptable, but I've been enjoying my kit nontheless.
And the Notch coil is absolutely fantastic. I find myself taking much short hits because of the short ramp up time and the flavor is amazing!
So I can use it in cubis also.
