The only thing I don't like about it is you can't effectively drain the sprue wax out using lower temperatures because it will catch fire in the kiln at high temps. If you try to flip the button upwards, wax shoots all over the interior of your kiln as it boils away along with the remaining water in the investment.
I have heard of casters doing a low temp burnout in an oven to melt out the wax before placing the flasks in the kiln to save wear and tear on their kilns. The goal is to melt out the wax instead of vaporize it. I wonder how well that would work in this case with a wax and resin mix.
