Easy to use, easy access for students with accessibility needs including those who are blind or visually impaired using Braille devices along with large font text allows me access right from my computer without having to rely of physical copies which I love! Nothing so far but please add option between Kindle vs iBooks in your website as it is hard (maybe impossible) sometimes if someone wants both options available together and there isn't an obvious way out? Consider this also when adding new features/chapters etc into future releases - we're very interested in these types of software's and would be happy customers otherwise!! Accessibility-friendly platform that provides textbooks at no cost while allowing us to purchase them later should our budgets allow it all makes sense why they'd want more people subscribing instead of just relying solely upon government grants The customer service is great! I have no complaints. I recommend this service to anyone looking to have a textbook solution. There are plenty of options to choose from. I think the pricing is a bit steep for someone like me who only needs a few textbooks. I have saved tons of money by using this service. For the price I pay, it is worth it! The cheapest option is a bit steep. I recommend going with the student option. I have saved over $100 on textbooks this year alone.
