Apart from that, I don't think there's much pointless gadgetry in my kitchen, apart from the usual blender that's never used sitting in a cupboard. Sometimes I think people shouldn't bother taking those with them when they move; if everyone did the same, they'd just find one ready & waiting to be ignored when they move into their new place...
I had one when I was married. Might've used it twice? Left it behind when I left my husband. Eventually bought another one (God knows why, and actually he's probably not sure either). Didn't use it at all. Gave it away after a couple years.
Hmm... Just to clarify, I eventually bought another blender, not another husband.
