Good fun product. we appreciate the DIY engine side, very funny especially when dad or grandpa is itself handyman, at least the child can do the same. Very nice, not difficult to climb. The trailer is not too heavy, so do not interfere with driving. Good size for enfnat from 2 years old, my nephew and my son 2 years 3 years feast! We regret (but it is the case of any plastic tractor) plastic wheels that glide and do not have a super grip. It depends on the ground (a little hard if too many stones) I recommend.
