Pros : Nice shape, but!
Cons : Creative Paradise missed the design. The internal protusions are too steep. They have forgotten that the coefficient of contraction of glass is larger than ceramic. Thus, when the glass cools after fusing, the glass shrinks faster than the ceramic clamping itself on the internal posts. At the same time the glass on the perimeter shrinks away from the outside of the mold. Now the glass is clamped onto the vertical posts. Let's just say the posts were straight up and down then there is no way of getting the glass off short of breaking the posts off as others have reported. Now these posts are very close to vertical by bad design. If the posts had a more conical shape with a large flare out, then there would be forces that would help pop the glass out. Check some other molds and you will find highly sloped internal posts which will have a lower chance of sticking. Your other choice is reducing friction as has been suggested by using MR-97. I have not tried, so i can't comment.
Other Thoughts : I would not buy this mold unless it is redesigned. I have had all the problems listed by others. You may get 2-3 firing before the posts fail. You must rekiln wash after each use. Take no chences by reusing old kiln washed mold. The high shrinkage of glass on to the post will crack and fail the kiln wash even if it looks good.
