I was hoping the top would click on like my other Tupperware pieces. I quickly beat three eggs and a half of tablespoon of milk. It comes out of the microwave perfectly almost every time.I BOUGHT THE BIG BOWL, THE FIRST TIME I USED IT, I USED 5 JUMBO EGGS, 2 TEASPOONS OF MILD SALSA, AND 1/3 CUP OF SHREDDED CHEESE. I PUT 4 TEASPOONS OF WATER IN IT, MIXED IT UP AND PUT IT IN THE MICROWAVE FOR FOUR MIN. IT CAME OUT PERFECT ON THE FIRST TRY. NOT DRY OR RUBBERY ONE BIT. I WOULD HIGHLY RECOMMEND THIS PRODUCT TO ANYONE!It does what it claims to do. It handles the heat very well, you can nuke bacon in it and it comes out unmarred. Perfectly cooked an omelet without flipping.I love it! I use it ever day and for more than just eggs!!!Habe es gerade eben bekommen obwohl ich es gestern bestellt habe, super schnelle Lieferung und netter persönlicher Kontakt.Freue mich sehr über das Produkt und werde es die Tage ausprobieren.
