Years ago my pastor at the time had one of these and loved it. When I was considering getting one I talked to my mom, a fine Christian woman, about them. She told me that she had had one and had worn it out. Good enough for me; I wanted one. So far I have used it very little, just got it today, but have been impressed. The paper is a little thin, but I got it for what is on the paper not just the thickness of the paper. I feel certain that I will gain a better understanding of God's word with the helps available. By the way, I got my mom a new one so she can wear it out, too.
