Background: This item was purchased for a 4 year old (one year below the recommended age). However, my husband did all of the transforming.
Articulation: I agree with other reviewers that there are issues with the shoulder ball joints. It is not a very secure joint and the arms constantly come loose.
Durability: One of the wheels broke off the day we opened it. We didn't have it long enough for me to comment on it's ability to withstand day to day play.
Transformation: I would not recommend an advanced level mechtech even for a 5 year old, unless a young kid has LOTS of experience transforming these types of figurines. There are a lot of steps that my husband couldn't even remember without the instructions.
Appearance: By far this is the best looking Ironhide I have recently seen in stores. Considering that my son is a 4 year old Transformer fanatic that only knows about the "new school" transformers, this one is above the best in it's class. In MY OPINION, it's more of a collectible and not to be played with. It's too large and bulky, but looks GREAT!
Customer Service: Contacted Hasbro about the ball-joint issue and the broken wheel. With no questions asked, they paid for return shipping of the item, sent us a complimentary item (2011 NYCC Exclusive Marvel Universe Compound Hulk Figure), and they are replacing Iron Hide with another Advanced Level DOTM transformer (Starscream or Optimus). Their customer service is awesome!
