Although I have had this ice cream freezer bowl since 2008, it began leaking this time when I put it in our new freezer.  I was appalled to open the freezer to discover blue goo on the bottom of the freezer.  I have always stored this on a shelf when not in use.  While 8 years if good, I would expect a Kitchen Aid product to last much, much longer.  We have had our mixer (lift bowl) since 1974.
