Pros : I have made several little dishes with this mold. It is a very good quality and stands up to many firings.
Cons : None that stand out, but my molds and shelves perform much better after I switched to the bullseye primer.
Other Thoughts : Remember to care for your molds by making sure you store them properly after each use. I have shelving spaced close together so that the molds lay flat without too many stacked on one another and are not stored on edge.
