While the IDEA of assembling your own creatures is great, and our son loves putting together the various pieces to create new "guys," this toy is poorly made and will remain forever in our memories as a BAD idea. Our family endured 3 hours of frustration - both child and adult - because this toy is so difficult to enjoy. Each alien requires a TINY grey piece in order to be attached to another part or to the chamber. This is day 2 and several of these have already fallen off and some are lost (no extras are provided!) All the parts are so tiny and difficult to insert that the toy is not appropriate for a 4-year old's manual agility (or a 40-year old) Once we get the alien's parts in the chamber to "create" him, the dials become immobile. Once we mobilize the dials and turn the creation button, it's almost impossible for a grown-up to, as the instructions dictate, to "lock" the parts and the press the button to pop out the new creature. My husband has to come over and press the button every time. VERY frustrating. Many tears and fits later, we will not recommend this toy. Great idea, poor implementation. Definitely not age-appropriate, and definitely not worth $30. Get some legos instead.Get more detail about Ben 10 Alien Creation Chamber.
