Review: This works very well! Easy to install. Review: I use this automatically opening arm in my greenhouse. It works fantastically. It's adjustable for sensitivity. I have it set so it pushes my window open at around 25c. The warmer it gets, to further it opens. As it cools down in the greenhouse it slowly begins to close. I'm so impressed I bought a second one.
