That thing is a menace. When I use the turner, it makes the plastic thingy move all over the place. Can't get an accurate and stable temp that way!!!Has anyone figured out the reason for the plastic film under the thermostat. I mean it takes up a quarter of the incubator practically... I've placed that Spot Check under the thermostat and had almost a degree in temperature difference... I think the design of it was intended for use without egg turners because I've had to free mine up on a couple of occasions...
