I'm in two minds. I work long hours, but actually too long to use the sc. I'm out thirteen hours and on slow it takes eight, so it's no good for that. I leave early and I can't face fiddling about with raw meat at six am, nor getting up early to do it!
But, now and then, it's useful. At the weekend I did three loads of batch cooking, plus my lunches for the week, and the sc did the chili, freeing up gas rings for other stuff.
It's fine for chili, though I don't like boiled meat so I do brown it first and also cook the onions to cook in the spices.
It's also good for stock, can bung that on and leave for hours without worrying. I've done a reasonable tagine in it. And lamb shanks come out very well.
But I've decided, overall, I'm not a "meat in slop" lover, so for me, it's only useful now and then.
And it's hopeless for dishes without meat really as veg can't cope with that type of treatment.
