So happy I bought this product. Remote works perfectly. The kids love the rocking function and the USB or Bluetooth music. It is so fun, with a pedal and stick and hydraulic doors like a real Lamborghini. The speed is perfect, slow is comfortable for small kids and fast is like a faster walk so u can keep up. This has power to climb. Is very well built, im not afraid of it falling apart or breaking easily. Was VERY easy to assemble. I just got it so I'll update after using it for a while.
