For other devices, since I had bad luck with films, I could not decide which one to take me a long time. Then I came across a test in which the Mumbi films have good quality cut. Then I still dared to take it this cheap films. The installation was easy and the film looks good and fässt good. A long-term evaluation I can not give unfortunately. A little tip before quietly watch a video of the installation, to take your time and a dust-free room looking (A bathroom after showering is very dust free, for example).
