Pros: Working perfectly since 2012. Works in freezing temps as well.
Cons: Costs a little bit more initially. But then again, you get what you pay for.
I am a very satisfied Pullet-Shut customer. I have been using this door since 2012. It simply works no matter how cold it gets, even in Maine winters. The photo sensor and solar panel make the operation of this door effortless and reliable. I wholeheartedly recommend this door for everyone.
