Good and accurate model for curious kids to explore the layers of organs in a body by taking a toy apart and putting it back together. Initital 'wow' factor was diminished by a great colorful big picture on the box and a considerably 'smaller' (by comparison) model that came out of it. I wish the size of the figure was significantly bigger, but I knew the size limitations by reading the reviews when I ordered it. The biggest value of this toy for us was educational, that a kid CAN explore inside the layers of a body, organize the body parts on the body chart, and put them back into the model. There was LOTS of help required from adult, and at times only the adult could 'work' the toy and the kid got dis-interested if a step took too long. I am afraid the toy won't last long, as few prongs (that hold the hard parts) bent and and an organ or two tore/ripped off during the first use. The shell/skin and organs seemed definitely to small for adult hands, and sometimes to 'loose/fragile' and tiny in child's hands also. Kid are not gentle with toys in general, but they needed extra reminders of the 'squishy' factor of our internal parts. This actually was an added educational bonus for us, that it took patience and skill to put it back together (easier to take it out). Also, we could say that we need to be 'kind' and 'gentle' with/to our bodies, because they are soft and squishy inside and sometimes even 'breakable'. The kid seemed not to be 'grossed out' by the way the organs feel, and for that I am giving one extra star for the 'fun' factor with respect to the 3 star durability. If you play it "right", there is 'extra value' included in the package about the fragility of human life/body in general. Great begginer toy if you want to 'demonstrate' something following along  the included Human Body book or any other 'HB' book you might have. This was our overarching goal --- to have 'hands on' model to go along with what you read about in books at this stage of kid develpment when they are curious about their bodies. Overall it was fun to 'touch' and experience something that otherwise it is only flat picture in the book. It is yet to be determined how many 'full use' (in and out) cycles we can get from it :)
