I currently use it right now, and I think it's better than what i thought!
Many people told me that 1602n was going to be waste of money.. but it really works good!
I incubated 12 button quail eggs.. they all developed! it's just that I opened the incubator too much.. and it all died during the lockdown
I'm trying on the another button quail eggs, and I only opened it once in 7 days!
But the thing is that you really need a fan..... hatch rate will DROP DOWN BAD if you don't..
You don't need to buy expensive ones from hovabator tho... just get cheap computer fan/cooler
I'm using VERY TINY (i think 6vc..or sth) fan from laptop cooler, and it works great!
Oh, you also need fair temperature to place the incubator.. (I keep it in my room)
If you've met all the choices, then you will be perfectly fine!
