I bought it when my kid was 4 months old and right from the first day my son loved it. He was trying to hold it, throw it, watch me stack it. In 5 months he wasn't into stacking, but he liked the way the rings swirled around when he dropped or threw them on tiled floor. After all those dropping it still didn't wear out. He started playing with the rattle and then took the base apart from the holder and used to play with it. He finally started to play by stacking them and he still enjoys doing it after an year.
