I have been using this incubator for 3 years. Lyon Electric is thougt to be the best small incubator available. They hold temperatures extremely well. automatic water flow is fantastic. It is simple but extremely effective engineerng. My unit was purcheded used and is still in excellent condition. I regularly get 95-99% hatch rates from this unit. I do keep it in a room with centeral heat and air so there is no hugh temperature spike in the environment. It will hold 18 bantam eggs and around 36 quail eggs. I have never tried standard eggs but I understand that more than 12 large eggs do not turn properly. This unit comes with the turner motor and operating manual along with my fluckers thermometer/hygrometer. If purchased new these units run over $ 400.00. I also have several additional turner wheels and quail grids. The unit will be shiped as soon as payment is received. I do prefer Paypal but will accept a money order for this unit as it is not time sensative. Questions will gladly be answered. Thanks for looking.
