"Just okay"
I bought this book holder just the other day and so far am not especially pleased with it. On the positive side, it seems very stable and does hold a book while protecting it from splatter. Also, it is able to hold single printed pages in it, as they just stick to the inside of the acryllic surface, I guess due to static electricity. The negatives, however, are a little more significant. The way that the book holder clamps the book from behind makes it difficult to get books in and out of it. If they are very skinny you can just pop them in, but if they are at all wider than the narrow opening you have to prop it open with one hand while using the other hand to try to squeeze the book in. Also, and this may be a bit hard to describe well, the rear wing of the book holder that clamps against the books is folded over on top so that books get a smooth entry into the book holder. But it has a real rough edge underneath the fold, and when you try to pull a hardcover book back out it really scrapes it up. No matter what technique I try, I can't seem to get a hardcover book out of the book holder without chewing up the binding a bit. I've already gone back to propping my hardcover books up against a phone book to read them.

"not great for large spiral bound, good otherwise"
I've found that while this works perfectly fine for most of my books, it is not easy to fit the large spiral bound books into it.
I have 3 Better Homes cookbooks that have 1 1/2 inch metal recloseable spirals that will not fit with this product. It is nice for the others though.

"So good I gave them as gifts!"
I ordered SIX of these cookbook holders and gave 5 to other family members as gifts.

Reasons I enthusiastically recommend this product:
These holders are relatively inexpensive.
They are stable enough to hold a heavy book.
They protect a cookbook from random splatters--something I needed for my favorite new bride's cookbook, which now looks like it's been through the food wars!

This holder has other uses:
It holds a newspaper or floppy magazine so I can read while I eat.
It hold materials I need to view at the computer.
It holds notes or lists which need to be dealt with soon--they are clearly visible.

One suggestion: When sending this as a gift, enclose a note of explanation or the recipient will be puzzled. ("What is this thing?") It arrives shrink wrapped with no label.
