I found about about KOBO when I needed to replace my Amazon Unlimited membership. The ebook I ordered arrived within a few days. The size is similar to the Kindle, I like the textured back, and I prefer the placement of the on/off button. When the ebook is in sleeping mode the title page of the book you are reading is displayed, which I really like. It is easy to use, and it took no time to explore and adjust to the controls. I am finding a lot of free and low cost books in the KOBO app, using KOBO+, which is half the cost of the Kindle Unlimited. Overall I am extremely happy with my choice to make the change.
