Bought as a gift for my wife, she makes a lot of cheesecakes that the two of us never finish.  I thought it would be great to be able to make smaller ones, less waste.  The quality of construction on these springform pans are very dissapointing.  The top edge is rolled sheet metal and on three of the pans the edge is not rolled over all of the way.  This creates a sharp edge that not only can cut fingers but also causes the sliding metal of the spring action to catch and jam, making the release very ineffective.  Great idea, horrible execution.
