What is the most wasted feature of your home?

The main oven as I use a micro air and air fryer to cook. Tinned and dried goods are stored in the oven! ?

The dishwasher. I never wanted it in the first place.
It was a sort of nearly new gift.
I store my Tupperware type stuff in it.

We have inherited a massive pond. Looks lovely with water lilies etc but a great deal of work, and as it has a fountain uses electricity in its pumps.
