I was not too impressed with this product. I think my problems are related to the mixing cup and stir stick. They provide a medicine bottle cap and a tongue depressor. By the time I had it mixed, it was already setting up. I recommend that if you want to try this product, you throw away the mixing equipment and get a medicine cup and popsicle stick or wooden coffee stirrer to mix up the ingredients. (These items when bought in bulk would be less than 1 cent per item) Then cool the liquid before using to delay the setting time a little more. This may work, although this should not be necessary.
