A review for Circle stickers by Karl Heideman.
The stickers turned out great! If you're comparing like me to a CMYK laser printer to the final product: the color is a tiny bit more muted, whites are not as brilliant but all in all you won't see a huge difference between the design and final sticker.
My only complaint is that there is no easy way to peel the backing off. No cut or fold in the backing. It's literally a perfect circle with very clean edge making it difficult to remove the backing. Since I plan on giving these out to people it deters from the experience and ease of use.
