This product is exactly what I needed for the small print in my Bibles and other print. The variety of sizes makes it convenient for use at home, church or anywhere else! You do have to hold it up a bit from the page to get the correct magnification, which can make it tricky if you need both hands for your reading project, but in every other aspect I'm very pleased.
For the price, you really cannot beat this set. I do have a little problem adjusting it for reading, but I truly believe it is because my eyes are changing so much so I'm having problems focusing well between the long and short sightedness combined.
