Motor skills, concentration, perception and rhythm can be so good workout. The percussion is very simple but very stable. It is not so easy hands independently of each other and the feet to play in rhythms determined. And even if the child is cocky or anger must drain the drums keeps it out without any problems. Good value I find OK. It is sufficient if the child begins for kindergarten children, preschool and 1st class. It is also well suited for ADHD children because it supported control problems Playful.
