Anyone ever used one of these with any success?

I read bad reviews about them(and some like them) on Amazon. I was gonna get one but went with my $99 farm innovators circulated air incubator with egg turner, free shipping also.

I bought one and during the testing of it before i put eggs in, the temperature was spiking and going all over the place. Not to mention with certain eggs the lid will not sit on tightly (i have ducks). I got my money back and bought a Janoel-48 off ebay. So far it seems to be fine, the temperature of it is a slightly off, but stays constant, so the hygrometer i bought at the store helps to make sure i have the desired temp. It also tells me the day, automatic turns the eggs and shows humidity which is almost accurate. Paid $80 for it.
