I have never had an incubator before and I want an easy one to use with a lid that is easy to close.
For that maticoopx, I wouldn’t say it’s difficult to close, you just have to align it properly when closing. I think it was more of a user issue, although some sensor would have been nice to detect broken seal and alert somehow.
Overall I think a lot of it depends how many eggs you’re planning to hatch in the batch. This will limit your choices by quite a lot. Unless of course you get a larger one and use it with fewer eggs if you do plan like that.
