Query: A great & inexpensive toy!

My 2 1/2 month old son's daycare has this toy and they lay him in a playpen with it and he just kicks and kicks! He just loves it and it doesn't go anywhere because it is against the side of the playpen. He loves anything with lights and when he is happy he kicks his feet, so it is perfect for him!
