  1. Hi! I received yesterday my new Odyssey. I was checking all the specifications and video possible before buying it and I have to admit that is even better I expected. It’s my first ebook reader and I have several ideas to improve it with the time. I miss some more options in the internet main menu, like rss feeds. I also would like to be able to save my google, fb, readybility … user/password not to enter every time. It would be interesting to be able to disable some animations that I dont like that much, like the zoom of the cover before opening a ebook. It would be posible also to filter or have invisible the ebooks in your library already readed. As I said before, I am very happy with my device and I hope I could also help to improve it for new releases. Thank you 🙂


    1. Hello David,
      thanks for your message. We’re very glad to know you are happy with your Cybook Odyssey. 🙂 I will pass along your suggestions to our tech team, or you can send them directly using the contact form on our site. The option to disactivate the cover animation when you open a book is already planned and will be added via a future upgrade.
      Happy reading!
