very good, but not excellent

Benefits - Easy to install, even for people who are not born craftsmen. You do not close the door, the magnets go ideally to automatically Going through fast enough. Even pets get the function quickly, our rabbits have done it (which was not the case at the door, or was it ruined). With us, the door is always left open earlier, now a gap remains in the worst case open in the middle (if the magnets not close), pure fly the likelihood that insects is minimized.
Disadvantages - The thumbtacks go with us again and again out, this may be due to the timber and / or because they are too short. The upper hem is a bit torn. So I think that this solution holds only one, maybe two seasons with intensive use. If you do not go by fast enough, or in windy conditions, close the magnets not independently. We have no more mosquitoes than usual (on average one to two) had in the room than usual during reciprocation. However, the locking mechanism in the center is not quite as dense as, for example, an insect screen door.
Conclusion - Whether this solution is the right one, is probably individual. For us, it has proven itself.
