I have 2 newer models of lg one bought in Jan one in Feb and both of them work just fine and I've had 2 hatches in one and 1 in the other and I've had 80 to 90% hatches with each hatch I currently have 18 polish eggs and 48 EE eggs in one and 29 khaki Campbell eggs and 9 call duck eggs in the other I do not use the turner because having to turn the eggs 3 times a day means I keep a steady check on the incubators where as a turner I'd forget it
