My daughter and I both have been looking into these for a little bit. They are AWESOME! First time we tried just cracking the egg - they partially stuck. So we figured a light spray with oil - easy peasy, the eggs slide right out and look perfect. I may be buying a second set for my daughter's house, makes boiled eggs a lot easier with 2 babies. #RankBoosterReview #Sponsored #Mabolon https://www.amazon.com/MABOLON-Cooker-Silicone-Cookers-without/dp/B07BQP4N17
