These work well mostly. I have been having issues with them though. When I first used them they kept leaking, so I did what they said and dipped it into the batter. When it came time to flip them they got stuck to the silicone and I had issues removing them and cleaning the rings afterwards were a mess. I think I'll keep using them how I did the first time because even though they did leak they didn't leak that much. This is available on Amazon . I received this product at a discounted rate in exchange for a honest review.
