This gift was a huge hit with my son, who was 15 months old at the time of the gift but still plays with it almost daily 2.5 months later. Every kid who has visited, ranging from 1 to 5 years old, also loves it. I didn't realize at the time of purchase how forgiving Mega Bloks are, and these are especially forgiving because the pieces are only 1 or 2 units long. This was the first stacking/construction toy that my son was able to play with and is paving the way for other Mega Bloks sets and Duplos.
