I can’t really answer your question other than I bought the 3rd incubator and it is terrible- first time I used it it was fine after that the temps went crazy, it’s also very hard to regulate the humidity in it. I lost everything in this incubator because it could not keep stable temps.
I’d honestly advise against all the above unless you find people here with good reviews on any of them.
It’s worth paying the extra bit of money to get a reliable incubator.
After Amazon fails I bought the cheapest brinsea (manual) for not much more. It was way better and I had really good hatch rates even though I was hand turning.
I wanted a bigger and automatic turning incubator so I bought a borotto and there’s no real issues with it but I do regret not paying the extra money for another brinsea. They’re just very reliable and easier to use in my opinion.
It might be worth seeing if you can get a better brand incubator second hand if you really don’t want to pay the extra cash. Saying that buying them new means they come with a warranty.
