I think that's about it. The biggest thing is that it works reliably and closes when it's dark, not earlier.
Here are my thoughts:
1. I live in the PNW, so don't have direct experience with this, but if you go to the Ador web site and then to 'blog', and scroll down to testimonials, there are several people from cold areas who are pleased. One fellow from Ontario, Ca, where temps went down to minus 23c, etc.
2.there is a manual override, but I believe there is a way to crank it open too. I haven't investigated that, but probably should.
3.yes to both.
4.If you scroll up a few posts, I mention the external sensor that I installed this winter. I love it. the door closes at nearly dark; my chickens have been in their coop for at least 1.2 hour.
I highly recommend this if you aren't sure the built in sensor will get enough light, especially in winter.
