My incubator is by farm innovations, basically the same unit you bought. I've hatched several batches with it. I messed up the humidity with the first batch, badly written instructions. After that it worked as advertised.
Just don't pull a "me" and forget about them, lol. I was cutting hay one morning, came to the house for lunch. I kept hearing a bird in the house. So I'm walking around with my sandwich looking for a bird, wondering how it got in the house... I felt dumb when I found it. My chicks had started hatching and I'd forgotten them lolol.
(I had several fields of hay to cut, my mind was elsewhere)
