tricky to install; working flawlessly for two years
A bit tricky to install. Needed to re-engineer the way it attaches to the greenhouse frame and vent. Otherwise, this is a great device, working flawlessly for two years. Looking forward to many more years.

Work great!
The directions aren’t very clear so we watched a few YouTube videos and then it was easy.. I have a harbor freight greenhouse and some drilling thru the windows frame to anchor needed to be done .. it’s best to have the piston as retracted as possible and it being simmer I put mine in a jar of ice and then you can press the piston as far in as it goes .. then attach it to the mechanism .. use self tapping screws vs the straight screws that comes with it .. once in they work awesome!!

Just installed - update
It takes a bit of guessing to get the unit attached correctly. But the brackets actually did line up with the holes from the original vent brackets. So it's installed and now I have to wait to see how far it opens, and if it closes correctly tonight! So it's been installed now for a few weeks and it works great. It opens the vent at around 70 degrees. If it reaches 80 inside the greenhouse, the vent opens fully. Otherwise it seems that the opening is directly proportional to the temperature. As soon as the temperature drops down below 70, the vent closes up tight. I think it is actually closed much tighter than before it was installed. It really helps to regulate the greenhouse temperature. I realize now, however, that it would have been better to have a greenhouse with a vent on each side to really get the heat out. But that's another issue.

Now I Have to Replace a Window
Installed per instructions, worked for a month opening and closing as designed. Came into the green house last week, the unit was broken and it went thru the largest window we have, now requiring a window replacement.

First summer and it worked flawlessly on my 8x8 greenhouse with a 4x2 roof vent.

Installation for my aluminum frame greenhouse required some DIY brackets and cutting of the frame. Spent several hours on this. After installing works well: sensitive to the temperature change and has great opening at maximum range.
