The games are simple no electronic noise in the head (easy to clean machine with seat too), the seat hooks are slightly chiantes but already stronger than the other trotter, for installation against the wheels did not easy too hard and if you force evil, plastic white. Final account of my son (8 months old) love to be in it and his feet are flat when it trots and short, and it grows well its stability, it can stand a champ for a good time at the table saccrochant low.
