Horrible to assemble. Holes are not drilled where they should be. Parts are missing. My husband and my neighbor are having to engineer this thing to put it together. You pay a lot for it and it’s a tiny version of the real ski ball. Little tiny balls to roll. Not worth the money nor the headache to assemble it. No instructions. Just photos that you can’t tell what it is. Don’t buy this! I HAVE to make it work, or I would return it.
