We saw this in a toy store and my 4 year old asked for it. I ended up ordering on here for part of his 4th birthday. He got a few other bigger toys, but this was easily his favorite. He loves it and I am impressed by how informative and realistic it actually is. Just beware that it's not easy to put all those body parts back together once it's dissected. It gives you an outline of how to do it, but I still tossed everything in a bag until next time.
