5 stars for mold, 0 for the separator

Nickel molds to have 3 of the same size, not too big, which demold perfectly, by cons, the plastic separator for the checkerboard effect >> very disappointed !!
Ok, I tried that once and my cake was missed from A to Z, because I did not have the right colors, so my colors were unlike anything anyway (making dyes and gel Illiquid found in supermarkets), and I think my dough was too liquid but it has flowed under the walls, a massacre. The circles do not fully rest on the bottom of the mold, so that's already a problem!
I will try again with a thicker dough, but I think it will be a new ugly cake.
I put the picture of my disaster ...
