So unfortunately our slow cooker formed a crack, as I'm hoping you can see in the images. Thankfully John Lewis were able to replace it completely, so now this one is going spare and taking space.
The heating sleeve works perfectly, has four temperature settings and a timer, and is barely a couple of years old. The pot, being cracked, shouldn't be used as is but could be used with a liner (which had been my original plan if JL couldn't offer a replacement) or if you can find a new 6l dish then you're good to go.
The whole thing was originally £50 so potentially a bargain if you can get use out of it!
Collection from horns road, if you've any questions then please send them over!
