I've had my screen 2 months now and it has made a huge different. I don't see mosquitoes, flies, or any other flying critters in the garage. If you take your time to install - after reading instructions - it is easy and doesn't take much time. There is a reason they include the tacks (use them). After installing, I never roll it up. I open and close the garage door with no problems. The magnets are strong and will stick to metal doors going up and coming down - thus, use the tacks - and not a problem. It hasn't ripped and still looks like new. I will have to give it 5 stars and a 2 thumbs up.
