I purchased this for a Birthday present for my young Niece... and she had such fun playing with it. They have hardwood floors, so it was easy to set up and roll the balls on the floor. The set also came with a pouch so all the pins and the 2 balls can be put away. The pins are a little on the small size (8"), so im not sure they can stand on a grassy area. I would like to order taller ones for outdoors. But the small ones are fun for little kids!
