We were hoping to find an easy solution for our patio door. Our goal was to spend very little money to protect us from the insects that would fly though our patio door. We weren't able to install a full screen door, so this was a great alternative. The magnets work very well when coming in and out. However, the only downside is the visual appeal. There is a thick black line (where the magnets are) that now block the sunlight. It's a small compromise for the price and practicality. Good buy!
