The springform pan I bought for a friend who has "just a springform pan" desired. Thus, no restriction was given and I have at Amazon made my search. After some research, I found the Emperor springform pan with glass bottom.
The springform pan makes a stable impression and can be assembled easily and take it apart. The glass floor makes a strong impression. I like the idea to put a glass floor in the springform pan, because you so not have to necessarily take the sheet cake for serving (as had often difficulties).
I can not say anything because I have not even used the form for use or tightness. The recipient but said that it has this form been in a different size and thus was very pleased. The form is so far always been tight.
I would buy the form for myself also.
