I didn't really have any problems with mix book. I found it easy to use and they shipped it to me really fast. The only problem i have with my book is that the picture on the cover is not centered. It runs off into the binding a little bit. I checked back on the website and I have it centered on the page but maybe they didn't take into account the space for the binding. And the last page where the mixbook logo is doesn't bother me like it did to others. I didn't even notice it.
