This is a cool tool and I am pretty happy with how easy it is to navigate. HOWEVER it is not enough MB's per plan. I purchased plan one and was only able to create a book with 6 pages..Like Seriously!? I though about upgrading but the most MB's is 125 and looking at competitors their first plan is at 150MB. I unfortunately purchased with credits or I would refund because it doesn't really fit what I need but it's not a bad tool.
