Delivery and packaging were quick or 1A !!
The film can be easily cut with a scalpel in the form. One should have a good background (old wooden board) and, for example, use a spirit level to mark.
The attachment of the film is a breeze. Simply having a water-detergent mixture moisten the (previously cleaned) window, start the film and attach a puller downwards. Then still with a scalpel to cut off the excess foil and hand finished. Compared to home improvement or IKEA goods clearly better (albeit a few euros more expensive).
In terms of light transmission very good indeed. It is quasi daylight in the room at the same time privacy.
Just buy it !!
