Not good
I read a lot of books... Google books are often cheaper but I cannot recall the last book I have read in this app that did NOT have section that just will not load. I am tired of skipping 10 - 20 pages in every book I read. I have an iPad 2 as well as the newest iPad mini and this issue is on both machines. I think I will simply switch to Amazon and kindle. It is also not as easy as it should be to search and purchase new books. No direct link from your bookcase and looking for the right link will often send you to another useless page and not the "shop" section.
