My eyesight is not what it used to be, and small print is very difficult for me to read. I am an avid reader, and every once in a while I come across reading material which is in small print and not that easy for me to read. My husband picked up a magnifying sheet for me to help me when reading material, such as books, that would be difficult for me otherwise. The size is 8 and 1/4" x 11", and it is unbreakable and scratch resistant. It does a fairly decent job of magnification, but it is somewhat uncomfortable to use because I have to hold it a certain distance from what I am reading, and keep it there. Holding a book with one hand and holding the magnifier with the other is not the most comfortable of positions, but the magnifier does do its job. It seems to be very sturdy, and since it is the size of a sheet of paper, it does cover a good amount of reading material.
I gave it slightly lower marks because of the inconvenience of holding it when trying to read a book, but it does its job and magnifies nicely, which is, after all, what it is meant for.
