Title: Great idea - fabulous update from the traditional circuit sets!
Review: Bought this as a Christmas gift for my 7 yr old son. He was unimpressed at the sight of it but once he understood what it could do it was "amazing" and he's using it regularly. Easy to follow instructions. He's even just recreated the pictures. Just keep in mind that you have the set or you may find yourself wondering if those sirens are headed to your house!
