The overall impression of the fly screen, for me as a little "cheap" is. Is just nothing special (what one expects from a Universal flyscreen ?!)
While it fully depends ultimately his job at door / window, "sticks" relatively fixed on Velcro, but justifies it simultaneously but not the relatively high price for some much cheaper competitors. Because unfortunately it rips also a very lightweight, making unwelcome openings for small pests (flies, etc.) arise.
Here you pay is definitely for the brand in itself and you should know before making a purchase.
Therefore, only "good" 3 stars for a product which, although working as it should, but is set far too expensive for my taste!
