Lékué Microwave Cookware Red Silicone Omelette Maker 1 "Disappointed" Mrs Bray 17 September 2018 I bought this on the back of the good reviews. However, I prefer plain omelettes and on the two occasions I have used it (without fillings) I found that although they are fluffy in the microwave and almost burst out whilst cooking,they become as flat as the proverbial pancake when removed. I wish I had not been tempted to waste my money. It is back to the frying pan for me!! A note from the team You could try cooking for longer at a lower temperature, thoroughly whisk to incorporate air into the eggs and whisking them straight before they're cooked instead of leaving them for a while first.
