A fun manipulative, especially if you just can't 'see' the unfolded shapes in your mind. The manipulatives make simple geometry problems easier. I think it's great using these as toys with young children--using the correct terminology of the shapes while playing.
The lids are a little flimsy--I worry about breaking the two tiny plastic tabs that keep the lids in place. The colored shapes are thinner than I thought they would be and only hold their shape while inside the hard case. The overheads were scratched--but I didn't want the hassle of returning them. The dark colors were easy to see, however the lighter colors were difficult to see; I'll have to go over them with a darker permanent marker.
Overall, I like them and would buy them again.
