I've done a quick google search on springform cake tins being vulnerable to breakage but haven't found any obvious answers.
My new replacement tin has just become a bit useless after just one use.
The same problem has happened with this one. The base fitted super snugly and tight to the frame when clipped in. Now, after making just one cheesecake (not even baked) I've washed it and tried to put it back together to store away and the frame, when clipped, just doesn't hold the base anymore - you can just push it straight though.
I thought I'd been really careful using it. Haven't done anything to cause it a load of strain to make it bigger.
Why does this keep happening to me?! Bought myfirst one from M&S, second from Tesco. Neither were cheap ones.
