I really like the look of them, you barely see that they are in-front of your windows. The measurement process was hard. Installation was pretty easy. I bought them for noise reduction but i think they weren’t as big of a help as i hoped for. The road noise like cars zooming by and motorcycles etc is maybe 10-20% reduced but i still clearly can hear them. Especially the noise of cars with loud engines ( or bad exhausts) is clearly hearable. My whole bedroom is facing the road so the noise might be also coming through the walls- I can never know for sure. At the end overall it might help a little with the noise reduction but was not a permanent solution for me to try for other rooms in my house.
