I got this no-name incubator a few days ago in the mail as a surprise birthday gift from my uncle and aunt. Since it didn't have any name on it, or on the unusually translated and vague instructions, I did some research and it looks like some version of a JN8-48--a chinese incubator. I turned it on and it is extremely loud, vibrates excessively and the cheap, flimsy egg turner came broken. It also came with styrofoam shields to insulate it, which I think I will use because it can't seem to hold temperature--it keeps fluctuating. I don't want to look a gift horse in the mouth here, but this beats my Little Giant any day for cheapness! Has anyone used this incubator before, and if so, do you have any tips? I can already tell it's going to need a lot of adjusting and tweaking!
