Indeed produces very high quality touch screen of the 3DS XL is still working perfectly after installation and the film is not seen nothing and naltère colors or anything else. But the installation is not so simple if one is a novice. It will take an area of the film and then shoot protection while supporting with CB (diagonal) Very easy when you have the knack. Anyway there are 3 protection sets for 2.50 euros, enough to lead you to that pose. And who else could test more expensive protective films, it nentait nothing easier to ask.
