I can't stress enough how much I dislike these pans.  I bought a set that came with two 9in. round pans because they were cheap.  You get what you pay for.  They don't bake even.  No matter how slow I bake my cakes they stil burn around the edges.  I have some other pans that are commercial quality pans and they never burn and always cook even.  I will never buy these cheap, poor quality pans again.
