Of experience, I would say that the only thing that might be missing metal reinforcement in silicone to the edges of the mold four quarters and two round pans. Why? Because if the molds are copiously filled, they are more difficult to handle. To work around the thing, think about putting the molds directly on the plate or grid future that will go in the oven, so you will not bother to move when filled.
In short, that's good. JOperation such utensils for quite some time now and I needed to complete the range. The current price (19.99) is correct given the number dustensiles included in the set.
