I bought this film to a bright display to darken (even in the weakest setting) of a clock radio. For the low price, it was worth a try. Unfortunately, the tone is too low for this purpose, even if you double. The application and the adhesive properties are simple and good. Is a bit annoying that the film already unpacked in the border areas had some kinks, a good part of 30x60cm is unusable, this is my main reason for the moderate vote.
