Excellent sensory toy. Out of 12 textures, I found 4 (two types of textures) to be similar; others were very unique. On the first try my 4 year old guessed 8 out of 12 (and my mom guessed 12 out of 12). It was a great tactile game to slow down and focus. As for other reviews, there was an unglued strand of carpet in the carpet block. But I've worked with carpet and find it almost impossible not to have some random carpet thread somewhere, so I don't see that as a terrible downside.
