Excellent. Excellent. Excellent Customer serive. Excellent products. I first purchased an Iphone shield, a laptop shield and I miscalucuated the measurements of my desktop. I contacted Customer service and they immediately handled the situation. The response is faster than the speed of lightening and they are so polite and kind and understanding. The products ROCK!. Every since discovering how dangerous these blue lights are to our biology, I went ona quest to find the best blue light shield. I chose Ocushield because of the science behind it and because they stand behind their products. I have these shield on all my devices. I noticed my eyes are no longer strained, the irritability and insomnia is gone when I stay up too late on these devices. And I know I am protecting myself and my family from these harmful man-created blue lights. I highly reccommned these products from this company. I would give them a 10 if I could. Thank you for all you do. Happy Eyes:). I am telling everyone about these products and your company.
