Hmm,
Aqua Cube hot water - used once, stored for 18 months then dead as a dodo.
Those mesh toaster thingos
Table (was replaced with a Drifta table which was way better)
Half the stuff in the kitchen drawers which we have hardly used
Electric blanket (SWMBO would violently disagree with this)
That's all for now, I'm sure to think of more.
