We have so an insect repellent and mosquito nets have bought them because of the good experience for our second door. Our first stops are already 6 years and has no signs of wear. The fly screen is made of fiberglass and is very tear-resistant and stable. The aluminum profiles are painted and with a film which should be removed after assembly gun. The assembly is something mühsehlig there with us all aluminum rails had to be adjusted as the assembly took about 4 hours. It is worth but when you consider how long the door then stops. At the door, two magnets to hold the door. The magnets are designed such that the door zuhält very good, but our cat with the head can not be pressed. We are very satisfied with the purchase and would buy the product at any time.
