It is with great reserve with respect to comments already posted I ordered these screen protectors, customer brand for my previous laptops I've never been disappointed. The delivery time is relatively long course (9 days) but the pose and very simple if you follow the instructions carefully to avoid the presence of such dust (humid atmosphere in the bathroom). Once installed, the use of s-pen seemed actually very difficult (sensation of writing with an eraser) but however, after cleaning (I think glue residue) and weathered protection with the supplied cloth special LCD cleaner, the end result is more than acceptable. Today, after several days of use, I am very satisfied with this product.
