Henrietta does a good job on hard boiled eggs if they are the right size. Sometimes she does not get them quite done. I love the design and the fact that you can walk away and she will let you know your eggs are done. I think they should design her to automatically shut off when the eggs are done. We have not had any luck with our soft boiled eggs. We can't seem to get them done exactly the way we want. I am still experimenting with the timing and the level of water. She also seems to boil over quite often, which makes a mess on the counter. I have learned to put a towel under her, this usually happens when I am making hard boiled eggs. I fill the container full, but sometimes the yolks are not quite done. But if I put anymore water in her she makes quite a mess. I still use her quite often, we love deviled eggs and she makes them so quickly. No water to boil and no pan to clean up, just wipe her clean.
