A random internet person said it was good for pre-geometry (upper grade elementary) or a geometry supplement.
I found a copy cheap and, being in a MUST HAVE ALL THE CURRICULA mode, ordered it. Having read through a fair amount while the kid in the back seat was taking a two hour nap (!), my thoughts:
The schtick of this guided investigations book is that one uses patty paper - those little papers that separate hamburgers - to do a variety of geometrical transformations and so on. Patty papers are a) foldable b) dirt cheap c) squares d) translucent, so you can easily trace lines/objects. The book secondarily seems useful if you're trying to improve object rotation scores on aptitude tests, since that's a lot of the exercises.
I think the notion of using it for pre-geometry or a supplement is right. There do seem to be a few homeschoolers trying to use it for a full geometry course, but it is IMHO unsuitable. No formal proofs, and most of the book is experimental guidance. (There's a companion workbook I haven't bought which may alter the experience, though.)
Tentative 3/5. Will modify if I wind up using it with the kids sometime down the road.
