Review: Works great once you figure out how to assemble it. - Previous reviews suggest drilling is not required, however, on my polycarbonate greenhouse I needed to drill holes on the upper window frame to get the brackets to line up in the correct way so that the window opened. My initial installation using just the brackets didn't work - the hinge was either stuck shut or stuck open depending on how I attached it. Watching the YouTube video is a must before you start as it's really useful and ultimately led me to realising why it wasn't working and that I needed to drill two holes to attach the bracket in the correct place. Now it is fitted correctly it feels very sturdy and works really well. Happy with my purchase and it looks like it will last a long time.
Review: Stronger than it looks - Fitted this to an Eden aluminium greenhouse. The only problem was the depth of the frame that the roof window closes onto - 4.5cm (where the old window stays used to fit). As the bottom bracket has to be fitted under this frame it means that the window bracket and sill bracket of the opener are 5cm apart before they start moving. If you watch the manufacturer's video, the upper and lower arms are parallel when the window is closed. It should open to 45cm but the best I've achieved so far is 30cm at 35C, which may be because of the design of my window. Other models of greenhouse may not have this issue.

### ⭐⭐⭐⭐ Good, sturdy Autovent
*by F***S on 4 April 2022*

This is a sturdy, powerful, autovent. It works well. I've knocked a star off because the instructions could be better! They refer to a hole on the autovent that is not even on the product, and generally are not very helpful. Perhaps it's the translation from the original Danish? I don't know. The product is really good, once you've figured out how it is best to fit it. I recommend the product, but not the instructions in English.
