constant freezing and trouble loading constant freezing and trouble loading. can barely use. absolute horrible waste of money. Need these books for school. Offered through my university but just a gross waste of money. Constant error messages saying the page is unresponsive just when trying to read through the chapter. terrible terrible terrible. It's been 2 years. I've reported so many times and they keep saying they are working on it. Refuse to give money back.

I hate school Asks to verify email, does not send for like 10 minutes when im just trying to do my homework from a textbook i paid 80 dollars for. You guys are ridiculous, why am I verifying email for a book, who tf wants info to a book.

Great resource I've been using Vitalsource since I discovered it in 2019. I was tired of carrying around textbooks and at the time most eBooks were still on Adobe's Digital Editions software, which was a very barebones reader more concerned with DRM protection than offering an actual reading experience, to put it nicely. When I mention Vitalsource, I'm referring to two things: 1. The eBook store, and 2. the Bookshelf app that they author. The Store --Selection The VitalSource store has a good selection of textbooks. Most books you'd need for school (or supplemental learning) on mathematics, physics, and computer science authored within the last 10 years are there. --Purchases and Refunds Purchases and access are easy. Most books have both rental and lifetime purchase options. The options seem to be dictated by the publisher, so every once in a while a books is rental only or lifetime only. Everything is laid out on the product page and I've never run into any errors. Prices are competitive with Amazon and other retailers. Refunds seem to be automated, so as long as you haven't already read more than 20% of the book, haven't returned the same book in the past, and haven't already returned 3 books in the last 90 days, you can expect a quick refund. Sometimes books from certain publishers or delivered by the publisher cannot be refunded. This is all detailed in the return policy. The Bookshelf app --Features and Performance The Bookshelf app's feature set has stagnated in recent years, and I stumbled on this page because I was looking for a way to report feedback on how highlighted notes should have better UI, but the desktop and web apps are good and by a country mile the best DRM reader out there. It's even better than the Kindle app - step up your game, Amazon. As with everything else in life, there are some weaknesses. The desktop app is a memory hog. This might have to do with existing DRM protection implementations, but if not, performance in this aspect can be improved, and may be the reason users with lower end hardware face issues. Conclusion Vitalsource has a great marketplace and offers the best DRM reading app available today. They're not perfect, and the app has weaknesses that regular PDF apps like Adobe Acrobat or Readdle's PDF Expert don't have, but it has more than enough features and is stable enough to rely on for daily use. Well worth checking out if you prefer eBooks over paper copies.

Not user friendly The website is not user-friendly at all, very slow and cumbersome to scroll through workbooks, doesn't even offer the basic function of showing 2 pages at once like most other services which makes using it for question practice extremely painful having to flick back and forth between pages. Wish I had never purchased the workbook through the website as it feels like everything takes twice as long.

Software Malfunctions Software Malfunctions The more you use the software's features, such as highlighting and cue cards, the more it begins to glitch and eventually becomes dysfunctional. Customer support states "It is a known issue" and has no fix. Their recommendation was to "delete highlighting" and be "more judicious" with its use. As such, I am being very judicious and never using it again.
