7 inch conpact CCTV For reading for low vision

7 inch compact CCTV. You can change the color and contrast to read documents or books. I didn’t end up using this as much as I thought I would. So basically like now. Great gift for someone who is low vision or legally blind, and has some usable vision, but just needs something to help them read also, would be great for someone minutes maybe elderly and their vision is changing
