I seem to be among the ranks of those who experience leakage! I received this attachment as a gift a couple of years ago, and have only used it 4 or 5 times. I don't store it in my freezer, as space is limited and I don't use it all that often. This most recent time, I found that it sprung a leak one of the sides! I love my stand mixer and all the other goodies I've purchased for it. This attachment has done it's job well when I've used it, and I am sad to see it meet its demise!
