I had to buy a replacement for the original that came with my Evo Magnifica because the carafe part cracked when someone unfamiliar with the machine used too much force trying to detach the frothing/steaming mechanism from the carafe. The two parts snap together and there is a small plastic notch to lock them together. Forcing the two parts with too much strength to snap them open or closed in the wrong direction can cause the the carafe to crack.
