Thank you to Step2 for letting me test this item as part of the Step2 toy tester program. My son went nuts when he saw the box in the driveway and helped me put it together with his "tools". It took us less than an hour and we decided to put it in his playroom for rainy or hot days. He loves it! He is burning lots of energy on it and really enjoys the periscope, which works great. He's obsessed with Paw Patrol and likes to pretend he's in their lookout tower. It's on the small side so good for younger kids or small spaces. Five stars!
