I'm another GGS user. You enjoy far greater clarity when reviewing your images on the LCD, especially useful when magnifying the image to check on sharpness. There is a downside but one I'm happy to accept because of the benefit described above - on bright sunny days the GGS cover is very reflective. Just have something to hand to provide shade (sunhat?!) so you can properly review the image quality, histograms etc. As others have said they look good - far better than the Nikon cover and there is no dust. Great value!
