Not perfect fit, Service of Mumbi absolutely top!

The film itself is very stable and can be applied very well, so it slides almost by itself on the display, and also sticks easily. But (and this is a shortcoming): It is not fit!
It is a good 2 mm horizontally and vertically narrower than the display. That's not the problem. The picture of the display not quite fill the the Wii U controller screen. If, however, this little piece of information has not been, you is right on the edge of the screen (in my case at the top), the protective film on. Result: The edge of the film coincides with the bottom of the display representation limit. This gives a clearly visible rainbow edge on the lower side. That really bothered me, so I took the sheet and tried again, because it was over. Dust has made the film unusable immediately.

A second film was indeed in the set. Now I knew how to do it, the film got 1m set well below the top of the screen; straight (even goes quite well) and lo and behold: The display is perfectly covered, the film is visible towards the edges by limiting, perfect!

But pity! If on the package an indication existed, I would have the first not accidentally destroyed. Basically settled only intended for training purposes with due lack of information, the second film. Therefore, only three stars.

Supplement: After we have given our assessment, the company has Mumbi phone set us (!). We have described the above designed case. As a result, we were delivered free replacement. Could not be better! This is a service, such as one no longer is it today used to. Here the company assumes full responsibility for their products and is well aware that ultimately counts the opinion of the customer. For that I correct my three stars to a full five.
