Original sound of our son (and during the visit to Legoland on the occasion of his birthday): this is the coolest gift I've ever received! And that's saying something ... shortcoming are certain defects in workmanship, the folding mechanism is extremely strict and the brake light (coolness factor 10 of 10 after Sohnemann) has a loose connection (we must look only times whether we can fix the). Otherwise "horny part".
