Electric Big Toy Drum Set For Kids

Bought for my 1year 8months old son (20months old). He and his grandma have a grand time using this. The seat is small but he is big for his age. The product says for 3+ but i cant see where they would fit. Putting it together was fairly easy and requires some force to snap pieces into place. Please buy your AA batteries before hand because your kid will want to play as soon as its together. I like that i can switch the sounds. I keep it where it only makes a sound when touched (there is an option to let it play music on its own) The microphone only works when it is basically 1/4 inch from his mouth. I like that its lightweight so that i can move it around. (UPDATE: My son moves it around with one hand now) I put it together in maybe 10-15 minutes. The tip of the drumsticks are foam which...my son likes to bite, i dont know if there's a production fix because if it were hard plastic i know he would bang up himself and my furniture hence i monitor him. It is plastic but makes real drum and cymbal sounds. The little blue piece which on the box is red is a problem to me because my son just pulls it out with the mic. Its overall a great purchase so far.
