Last year I was offered a free 16×20 canvas print by Canvas Champ if I wrote up a critique. The print I got was built nice but the quality of the printing was a little lacking. But, I gave them the benefit of the doubt and wrote a constructive review: UPDATE!!! Product Review: Canvas Champ Prints.
A few months later I had them print one of my images 16×24 for a client and a 16×24 of my father-in-law as a gift to my sister-in-law. They were both atrocious. I was not happy with it at all. So I updated the blog posting. Again, I was fully honest with the critique.
