I bought this screen protector set to use on my D850, and D500. There are so many options for this sort of item on the market, it was daunting to pick what I believed to be the best option. What sold me on this particular item, over others, was its 9H hardness level, tempered glass, versus some form of plastic composition, and the kit containing all items for three attempts at a perfect, bubble-free installation. Each glass protector is well made, has gently rounded edges, and comes with an easily pealed back cover, for the side that adheres to the camera screen. I’ve never been very good at installations of screen protectors, but I installed these on both my cameras, in one attempt, with no bubbles, and with proper placement! Yes, there is a slight, maybe 0.5mm gap along two sides, between the protectors edge, and the camera body’s edge of the recessed lcd, but this is ok, and is a necessity. It provides the slight margin of error to guarantee fit, since variances on different camera units may exist. It is not a large enough gap to concern oneself with. These do not, in the slightest, affect the touchscreen’s usability, and, to me, I love how it provides a flush finish to the lcd screen with the surrounding camera body. These are the exact thickness to provide a seemless, flush transition from camera body, to lcd screen front. I am so pleased with these, that I purchased a backup set for the future, should I damage the ones installed on my cameras!
