My son is almost 4, and loves TF animated. I was a huge fan of G1 as a child, so this is a special time for us to enjoy together. For his birthday, I already have Deluxe Prime, Bumblebee and Prowl put away. They said 5+, but he is really good at taking care of his toys (good enough that I trust him to play with my G1 bumblebee once in a while), but I have read on some of the toy sites where reviewers have said they should be for 7, 8 year olds at a minimum. I do not want to give him something that he will get frustrated with. To folks that have them, are they difficult to transform, or easy to break? Again, he is fairly smart for his age, and he is careful...probably handling his toys at a 5 year old level. Thanks for your comments.
