Hey there
I got one of these for Chrissy from my MIL. It is Tiffany brand.
I was sceptical but after giving it a go am so impressed - does the nicest most tender roast chicken and veg too in about one hour! Given it has been hot I have not tried much else in it. Given my oven is floor level and my 18 month old is into everything at the moment it is a safe baking option!
It is easy to clean but I would not say it cleans itself!
HTH
