They are great you just put them in your crock pot. I think they are made out of the same thing as turkey roasting bag.
I have a smaller crock pot and a huge one the liners fit in both. You do not get the burning/sticking that sometimes happens in slow cookers.
When your meal is done and you put away the leftovers (if any) you just grab up the sides and toss in away. At most I have to do a quick rinse on the crock pot mostly because I feel like I should not because it is dirty.
Best invention ever I am a big crock pot cooker and start all sorts of things before I leave for work so I am not stirring it during the day to keep if from sticking. With these I don't have to worry about it.
