Today I enjoyed my third soft-boiled egg. Really enjoyed. The first time was a bit too long (6 minutes, almost hard), the second time a little too short (just 4 minutes). Now today the perfect egg (size M). This result I reached (the yolk runny, the egg whites just firm enough not to be gelatinous) today with nearly 4 1/2 minutes at level 3 (out of 6). According to the manufacturer 53% of my 750 watt microwave. In no event shall the egg had burst or leaked. I do not have pierced the egg. Also, the material and the appealing exterior has convinced me.
Can now recommend this product well, good appetite.
