25 euros down the drain.

So there's 2 stars, because the product determines that does what it should, because if you manage to capture the film flawlessly on the screen. It appears wertig, stable and non-reflective at first glance too.

But now comes the big problem: Installation and instruction.
Slide number 1 I destroyed because I was not quite clear through the guidance of what to do now.
The Erlecchtung came only after I had this broken down into its individual parts. That leaves a film.

In Slide 2 I now knew how should work the principle problem was merely that it is almost impossible so to fix a big film without air bubbles or dust particles. The credit card-sized piece of cardboard, which you should take to help the trapped air moment during the laying sweep away the film is my Meinugn after a joke. On the one hand this is much too fast for (cardboard), on the other hand, the fight against bubbles is so vain. Whenever one pushes the bubbles above them come down again and vice versa. A type ruler, which has the width of the screen would have been a better solution here afterwards. Maybe it would have worked then. But well, what can I say. After 2 attempts is final. For the next test you have to shell out 25 euros again. In my opinion, the product is therefore also too expensive for 2 films .....
