Ive been incubating and hatching in my Genesis 1588's....one for incubating, one for hatching. The one for incubating is terrific, its been on nearly non-stop for 18 months, and never misses a beat, never wavers on its temps. Its really great...holds a load of eggs too. But when it comes to hatching, its a mess. Doesnt hold humidity well, and its awful to clean. Cant ever get the styrofoam really clean, it stains, its cumbersome, just a mess. I decided to buy something else for hatching, and looked and looked and looked. Finally settled on a Brinsea Octagon 20. Ive had 3 hatches so far, and its wonderful. Extremely easy to clean, and cleans up to look just like new. I really love it. Highly recommend it.
