RedShelf has been the worst. It started with the price, I was surprised the cost was in US dollars, I only learned when I looked at my bank statement. OK whatever, my bad.
I rent a book for $60, get it for 180 days. I had to get it through my school, but I will be letting my prof know how horrible the site is.
I was pumped at first because RedShelf claimed I could highlight, take notes, and make flashcards, which I thought was exciting. Except none of those features worked properly for me. I was able to select some text, and make notes, but it was sloppy and ultimately I could not use the highlighting feature just because of how spotty it was working.
But then it got worse.
I went to start reading my 50-page chapter today, got about 4 pages in when it stopped working. The pages wouldn't turn. I've been trying to figure it out for an hour now, emailing RedShelf support with no help in sight. Like I just want to do this awful reading - can I just do that?
Somehow it got worse.
So I restart my computer, clear the history and cache, do all the little tricks they tell you online, nothing works. But I do notice now that the book itself looks a bit different - maybe it's fixed! No, it just looks different, oh wait, something is different, all of the notes I was able to take (however crappy it may have looked) are all gone. Hours of reading and note-taking lost. I honestly don't even want to use RedShelf for this, I'm not even sure I can, but I can't afford the text. This has been awful, I hope my teacher will help me figure something out.
Bottom Line: No, I would not recommend this to a friend
