Positives: The flyscreen is really almost invisible and will not be visible until you go get close to the window.
Attachment: Well, that requires a bit of tact. Attach tape to the window frame, mosquito nets on. Works! Tricky it is, if you (for example if the window is smaller than the grid) will cut off the excess sides. NOTE: patience and careful. The delivered this knife makes good, but we slip or not remains straight, one half the lattice pulls right back down with. Go slow and do not despair ;-).
Negatives: If you look closely, or opens the window, you can see on the window frame (if white frame) know that it is a be glued anthracite-colored end grid, especially when cutting had not worked so quite perfect - looks a bit cheap , So what. The plague is out there and how often looks the visit with you in the window frame ;-). Just!
Tesa flyscreen the great alternative to expensive insect screen frame.
