Bests & Worsts Reviews from Amazon

At first I LOVED this little oval pot! I use it all the time, but in the last two months, no matter what I make in it, the insert comes out with lines of junk and stickiness all around the oval insert! I can see inside the shell that something is happening while the insert is inside the shell and cooking. This is terrible!! I clean both afterward to smooth. But as soon as I do another cooking event, it happens again. I really want this to WORK like it did in the beginning and I don't want to CHANCE ordering a new one in case the same thing happens. I'm very sad because this is the perfect size for me. You will need to zoom in, if possible, to see what is occurring.
