It is not often that one sees book accessories advertised through YouTube. This little book holder is alright, I suppose. It is easy to notice some hesitation with which the inventor of the device talks about page turning. This is by far the weakest spot in any book holder. BookGem works great with Kindle and other book readers, but I feel like with those there is less pressure to use a book holder – they are much simpler to use, do the form factor.
