I have a Hova Bator 1603H and I couldn't believe after what I paid when it was delivered that it was styrofoam. I thought it was the packing material, but it was the actual incubator. Then I put it together and the wafer thermostat and the wing nut control were ridiculous-how can you get something like this to work accurately? You can't. It stays on all the time and will not turn off regardless of how much I turn the control (it is as tight as it goes). My digital thermometer which is fairly accurate always measures the temperature at over 100 degrees so I've yet to put any eggs in it. I keep trying to get it to the right temperature and humidity but its seems impossible. I have better luck with my home made styrofoam ice box and Ikea clear plastic tote incubators which keep almost perfect humidity after adding two small tupperware containers full of water and bacteria resistant sponges. I ordered an egg turner from CoopsNMore and had to return it because it was missing parts and they would not provide technical assistance. So I've been turning my 25 pheasant and 12 quail eggs by hand 4 times a day. Just 4 more days and I'll be home free! I'm ready to invest in a Brinsea depending on how many eggs hatch. I don't believe the GOF corporation is humane based on the quality of their products and the thousands animals that have suffered because of it. Not to mention the thousands of kids that have had to witness this cruel type of death over the years!
