Query: Not for me

I found the view screen very difficult to read. If the calculator was not held at a certain angle, I couldn't see the numbers at all.Don't know if they are all this way or maybe mine was defecive - it was out of it's wrapper when I recieved it. Also, this was my first scientific calculator and I found the directions rather confusing. I returned it for credit with no hassle.
