I have a very large crockpot and a very old one, which means the liner is not removable. I don't necessarily have a problem with food sticking to the crock but, because it's so large, it's a little difficult to clean.
I have used the liners and find them more than satisfactory. The food does not taste any different than it does when no liner is used. In fact, I used one when I made my corned beef for St. Patrick's Day.
I found the liner quite convenient actually. After I cooked the meat, I lifted it out of the crockpot with a large fork and, then, waited for the juices to cool enough for me to handle the liner. Once at that temp, I simply lifted the whole shebang out and poured it easily into another container. There was NO liquid, nothing left in my crockpot.
The crockpot seemed to have a tighter seal during cooking with the liner, too. Worked a bit like a gasket.
I have one just like that, too, Katie, and cleaning it isn't easy, even if the food isn't stuck on badly--it's just awkward. That's why I was considering the liners. Now I'm going to give them a try--thanks for posting!
I use them all the time and they are worth every penny. ( I know you can just soak the crock pot, but, when I think of all the water I have wasted, trying to get them clean). No more, just give me a bag.
I just recently started to use them. I have not noticed any change of flavor. It was a real time saver for a Super Bowl Party (melted cheese dishes); I need to stock up on them. They are well worth it!
