I have a Hovabator Genesis, my only complaint is the fan has officially gone out and I haven't had it long at all. Never seemed to work "great" from the start but it went downhill fast and has officially give up completely now. I'll probably just have my hubby replace it with a computer fan.
We use a homemade incubator as our hatcher. Its a styrofoam cooler with plexiglass top. Light bulb for the heat and a wafer thermostat. Works fine, have had great results thus far with it hatching.
We need a new water tray for the bottom, I keep two in there but one was cracked and I didn't know it till it was time to set eggs to hatch so I'm hoping and praying we have a good hatch. We have one pipped so far, they're due tomorrow.
