The user's manual was difficult for me to read. (I am 72 and wear reading glasses.) Also, the colors of my unit were completely different from the colors in the user's manual. With the small fonts, small pictures, and mismatched colors, it was a painius in my anius to follow along. However, I figured it out and the results were excellent. I just believe that a user's manual with larger fonts, larger pictures, and the correct colors would have the effect of not frustating new or infrequent users and making them happy to brag about your product.
