It's called Preset Chess. There's no need to set up the pieces, probably dropping a few in the process. The magnetic pieces go into little compartments in their starting positions. So by opening the box, the pieces are already set up on the board. You're ready to play within seconds.
When you're done, just put the pieces back into their starting position compartments and you'll be ready to play another game later.

Isn't the time-and-effort saved in setting up the board nullified by the time-and-effort spent in putting the pieces into their exact holes?

So basically you set up the board when you finish playing instead of at the start
