There’s 2 of us & ours goes on daily,sometimes twice😱, even if either of us were on our own we would still use one to it’s full potential. I’m not sure it does save electricity if you rinsed,washed & dried the same as the machine & the pots are certainly cleaner..well more so than if hubby washed up lol. He thinks just really hot water is enough & a bit of a swish with the brush.
