My nephew is loving this toy! After sitting with him a few minutes and showing him how it works, he's having no problem taking out the screws himself. It's not a toy that's super easy immediately. It takes a little work putting back together but isn't so hard that he can't do it with a few tries or a little help. I'm okay with that as it is teaching him to work with his hands and to not give up. It is made with good sturdy plastic to last.
He's been super busy ever since the car arrived. I love that there is the option of a battery power drill that really works well and a handle to use the screw drivers without the drill, so no problems with running out of batteries. I can see this will be one of his favorite toys.
