This is a screen protector designed to fit the Sony NEX-5. It is advertised as a pack of two; unfortunately I only received one but the supplier rectified this promptly.
The screen needs to be clean before the protector is applied. No cleaning cloth is supplied, which was a little surprising but I had fortunately retained one from a different kit, although I imagine a general lens cleaning cloth would do the job just as well. Once the NEX-5 screen was clean, application took a few seconds and bubbles were easily removed. The protector fits just inside the perimeter of the screen, so you need to work out the alignment before proceeding to apply. The result is a protected screen with no discernible impact on view.
The product fits my Sony NEX-5 perfectly and does provide the necessary protection for the screen. However, it makes some more reflections apparent when compared to the screen without the protection. Not a big deal overall, as the image is still clear in most situations.
