Lots of fun, takes some getting used to loading the chargers (one click does the trick), however my 6 y/o and 4 y/o have a lot of fun battling each others, and every once and a while I'll sneak in a game. There's a collectable component to this game, but it's not necessary. it's ready to go out of the box, and is well made, and attractively designed.
The stadium, and two launchers came complete, but the red bay blade was missing the metal core, so only one bayblade was able to be built, without that piece you can’t battle the two bayblades
