I was a little nervous, from the reviews, but my son really wanted these. I went ahead and ordered them, and I am glad I did. They are actually really cool! No, they are not incredibly durable, but I have a feeling most of the issues with durability have had to do with trying to rotate the pivot points beyond the set points. The way they collapse, there is an endpoint to the rotation. As long as you realize that, and the child realizes it as well, they work great. They are not really hard plastic, but for the purpose of a collapsible dinosaur, it is neat to collapse them down and open them back up again. My son is really enjoying playing with them. I warned him that they were "fragile" (they are not really, but that word goes a long way with him), and that if they broke they would not be replaced, and he has since been treating them with a lot of respect. The age 3+ might be a little misleading, as this is probably hard to explain to a 3 year old, but my 5 year old has had no problem learning how they work without breaking them. As long as you buy this knowing they are not a toy to be really rough with, I would recommend.
