I was initially very skeptical, since the bookstand but very very cheap looks in the pictures. Well, it's not a looker, but that is after all also not his job. Its mission is to provide books in a comfortable reading position and it makes perfect. Although the bookstand looks cheap and fragile, but holding my thickest ham (some with more than 1000 pages) without Mukken from. There are many settings in terms of inclination and you can also turn the pages super if you do not use the side brackets. So you can read and write both textbooks easily, as well as (when using the side brackets) from write without constantly having to use a hand to hold open the book.
I think there is more to say. Can the Büchhalterung therefore only recommend! For the price twice!
