I've got a Russel Hobbs. I cracked the ceramic insert and had to replace it. Their after sales service is ok. I rang them, they charged my card and the pot arrived a couple of days later.
It does seem to cook a bit hotter than some other brands. I usually knock a bit of time off the cooking times but I think that as it ages it won't cook quite so hot.
It's a 6l so it's big enough to roast a leg of lamb in - yum.
