I purchased this to test to see if zazzle was producing good quality.
Needless to say, they are.
The sizing runs a bit on the small size though. Print quality is perfect. What you see on the screen is what you get.

Ordered the Irish terrier t shirt. I love it! There was a slight issue with sizing ( my fault) but their customer service was amazing. New t shirt within 5 days. I recommend getting 1 to 2 sizes bigger. I am wearing Men's size large.
