"This is an excellent, affordable set for kids, but has plenty of character and rare/useful pieces for an adult collector. The design of Thanos' gauntlet car is fantastic (even if it's missing one infinity stone - I swiped a spare red piece from the Yellow Submarine) and both minifigs look great, and can be easily upgraded to "full height" characters with plain red/blue legs.
A few of the clasp pieces might be a little difficult for very young children to attach, but 10+ should have no problem."
