I got this as a gift and thought how cool. I can finally get brownies that are cut perfect. With this set you get four pieces, and a book of recipes. The directions read to spray the pieces with nonstick cooking spray before putting in the oven. Out came the brownie mix and i preceeded to make the brownies. The pieces fit well but i noticed that the pan for the brownie mix was unusually small. When the brownies were done they were small and not consistant in size. The ease of the divider did do well in separating the brownies. The pan set cleaned up well, (dishwasher safe).
My biggest problem was the leaking of the cooking spray on to the bottom of the oven. Problem: I didn't read the directions that said to put a cookie sheet or something under the pan incase of leakage. Next i had to clean the oven. Read directions carefully before using new produts to save yourself time and work.
If you want small brownies and something that will cut them perfect this is the set for you.
Update On Mar 10, 2010: These were priced around $20. at Christmas time and can now be found for $4.99 at The Christmas Tree Shop. The cost at the Christmas Tree Shop is even too much, unless you really want to try them.
