A final is not really going to serve me

Although in the ad it says that the bottom is "clip" it is not at all the case, the funds will just land on a ledge at the bottom of the rings forming the edges. I told myself that if it was marketed is that it must fulfill its function as is, but my dough cake by leaking a little below a mold. I may be exaggerating a bit by saying that it does not serve me, just that I protect the bottom of my oven and I put the aluminum mold around the bottom because it is not a big leak. This is because the leak was not violent I put 2 stars and not one, but it's still very disappointing
