This is a great idea - with squishy, removable organs, and the ability to see how all of the parts of the human body fit together. The plastic "body", however, is cheap, poorly constructed, and the organs can't snap into place the way they are supposed to, and the model splits apart because the parts didn't line up and snap into place. It's almost like the plastic is warped.
The accompanying book, explaining the functions of the organs is very good. My 4 year-old granddaughter is delighted with the anatomy book, but frustrated with the model's inability to hold together.
This model has potential, but is over-priced at $30.00.
