I've had this egg cooker for a few years but after getting it out again for the holidays, I just had to write a review.First, it makes perfect eggs. You know the perfect Martha Stewart looking ones with no green rings. That alone is fantastic when you're making eggs for company. Secondly, it frees up a pan and a burner and we all know that is priceless during the holidays. Just made all my eggs for dressing and deviled eggs in just minutes. No guess work, really no work at all. The cooker comes with a plastic cylinder that has a needle on the end of it. Just poke your eggs so the steam can escape. The cylinder itself is a measuring device for the amount of water to add. You just fill to line based on how many eggs and how done you want them. Turn the cooker on and it beeps when the eggs are done. And now your done! How simply is that!
