I purchased a technical engineering reference from Princeton University Press expecting to be able to read it on my computer through a web browser. Instead, I discovered that the eBook could only be accessed through a mobile app.As a practicing civil engineer, reading detailed technical material, figures, tables, and calculations on a phone is simply not practical. Had this limitation been clearly disclosed before purchase, I would have made a different decision.What was most disappointing was the customer service response. I explained that the product could not be used for its intended purpose and requested either browser access or a refund. Both requests were denied, despite acknowledging the limitation and inconvenience.I have always respected Princeton University Press for its academic publications, which makes this experience particularly disappointing. Buyers of technical and professional references should be aware of these access restrictions before purchasing.

This app has almost zero functionality to begin with, not allowing you to perform basic e-reader tasks like highlight text or swipe to turn the page. Of course, that's when it's functional. Now that I've been running it for a few weeks it has decided to crash every time I open it. Unfortunately, PUP doesn't let you use any of the better-designed e-readers with its e-books, presumably in a craven defense of intellectual property, which I must say it has succeeded in, since even I myself cannot see the material I paid for, and presumably will not be able to accidentally disseminate it by word of mouth. The ivory tower remains secure. Do yourself a favor and find a PDF.

USER BEWARE: This app crashes once every five times I open it. There is a known issue that causes an error message to appear stating “Email address not recognised”. Even after re-starting my phone and re-installing the app, I cannot fix it myself. I’ve contact customer service when this occurs and each time the reset my credentials, which allows me access, but I still have the issue occurring! Customer service does not work weekends, so support is insufficient. I paid for ebooks that I cannot access!! Shame on Glassboxx and shame on Princeton Press for using Glassboxx to host their ebooks.

Bought an ebook on this because of class requirements. I just bought the book 1 month ago, and I cannot open the book today to do my homework. I thought it’s internet issue or anything, so I tried everything to get it work, like restarting, use other WiFi, etc. Lastly, I tried redownloading the app, now when I login with my email, it said email address is not recognized. This app literally has only one job, one simple job, and it failed. Completely trash app.
