Fantastic product, very good quality and the kids love using it. The knife is actually sharper than some of my other kitchen knives. Our 4-year old has mastered using the knife and the guard after only a couple of attempts and now we are quite comfortable with him using it on his own, although don't forget that this is a very sharp tool and supervision is always required. The peeler is great too, our kids now peel most of their fruit by themselves. Our kids loved helping in the kitchen anyways but now it means that they can perform more tasks independently so they are even more eager to get involved in what is a fantastic bonding and educational/developmental activity.
