I am sooooooo impressed with how it worked and the biggest and nicest surprise for me was how easily the rod went through the cake especially when it went straight through foam core board I used between the 10" and 12" layer. Wow - it was a snap. The cake arrived assembled and all I had to do was pop on the fondant puzzle pieces. I saved considerable time. Oh, and the outside of the cake safe actually felt cool from the air conditioned ride which tells me how well it insulated the cake for the journey. This product of yours is absolutely fantastic! I look forward to getting another one in the future. I'll never take another cake disassembled again. The Cake Safe makes it so easy to stack and ready to go. Thanks so much for this fantastic design of yours.
