This toy may look simple but it is very entertaining for my 7 month old. It is terrific for learning cause and effect. The lights are bright enough when used indoors to really appreciate the drum. The two volume setting are great. There are 4 modes: 1 makes a drum sound when you hit it, 2 makes funny noises when you hit it, 3 plays a pleasant tune 4 plays some notes when rolled on it's side.
