multicooker [deep fryer, slow cooker, rice cooker (?), etc.] I almost never fry or slow cook and you'd have to cook a mountain of rice to make it worthwhile to drag out the silly thing. Anyone want to buy it? Make a bid!
Also, I'm such a sucker, I bought one of those things - as seen on TV - that are supposed to segment your citrus fruits for you in a quick turn of the wrist. Not! Will throw it in FREE with anyone who wants the multicooker.
I think we should all sell or trade these gadgets that haven't worked out quite as planned. I got rid of a number of them during my last move...but can never resist buying more.

Just bought a gadget that promises to sharpen my never need sharpening knives [until I can afford a good set of Henckels or something].
