What specifically makes it the easiest fillable cart? Cause from what I see, the “oil’ is bubbling as it sits, meaning low viscosity mixture, also from the looks of it, very homogenized with Mct. Also from your description this sounds to be a open cylinder coil, which with low viscosity oil, will make that famous pop n crackle, with thick oil, as anyone who’s used a dual quarts open coil “dab cart” you get the bubbler effect that ends up popping & shooting hot oil into the mouth piece/ your mouth.
I’m not here to hate just taking a observation.
