About a week and a half ago I decided to buy an incubator an chose a Hova-Bator. The one I ordered was a 2362, Turbo Air, with the Electronic Thermostat w/the Auto egg Turner. When they shipped it at the time the 2362 was on back order but did not show on the place I got it from so I got an upgrade at no extra cost. I got the 1583 w/the wafer thermostat. It is right on the money and does not need adjustment. I am much happier with the wafer then I would have been with the electronic thermostat.
