Was easy to install. The only trouble is I couldn't get the foam weather panels delivered to a Canadian address. I used plastic sheets to block the wind coming in through the screens. Worked well enough. In the end it can also be used to vent my portable AC. Definitely pricey but I had no other options. Review: Super handig - Gemakkelijk in gebruik!
