Very nice toy. Bought this for my son as we have been playing around with syringe hydraulics. The instruction could have been better and bigger in size. But it was quite straight forward to build.

Esta genial. funciona perfecto. Gran calidad del corte de madera. Muy entretenido el montaje sobre todo si ayuda tu hijo o hija. Ojo hay un herror en las instrucciones y fotos. la jeringa del cazo pivota en el eje mas retrasado, como figura en las fotos que pongo. Si lo pones como en las instrucciones la movilidad del cazo queda muy limitada
