Overall the listings cover roughly ages 2–8. Individual products use labels such as 2–6 years, 3–8 years, 4 years and up, and 5 years and up.

Some sets are non-powered, while motorized boosters are battery-powered. Examples specify boosters that require four D (4 D alkaline) batteries; other entries list only non-powered pieces.
