Bests & Worsts Reviews from Amazon

This is an engaging toy that wins on so many fronts but alas, they blew it. I wonder if perhaps this toy was down-sized from its original and no one bothered to re-engineer it once scaled down. For the pictured projects, only some of which there are enough parts to construct, pieces interfere with other pieces so they cannot go together or the wheels turn in the configurations shown. My kiddo can still put pieces together in ways that satisfy his desire to build but we will pitch the instructions to spare him frustration and disappointment.
