These take some getting used to but once solved are brilliant. First trick is to put hot or boiling water into the pot just before microwaving rather than cold. Then 30 to 50 seconds should be enough based on size of Egg (30 Medium, 50 Large). I also use the microwave plate from Lakeland to stand the pots on to make them easier to take in and out. So pop pot onto plate, crack egg into pot, pour a little water from a kettle recently boiled, close lid, pop into microwave 40 secs, take out hold and drain, open, loosen with knife if necessary, slip onto warm buttered toast - Yum yum.
