Not only are home made hoods cheap, they work better than the screens that are out there for sale. Some of the screens for sale look like a joke.
Home made screens might not be as convenient, but they work better. Just make yours deeper and don't forget the bottom. 3 sided screen only helps you 75%. There's still light and reflections coming from the bottom.
With Anti-glare screen sticker, my Samsung Tab Pro finally works great even on the brightest Sunny days.
