I'm very excited about the Extreme Roller Coaster but since it will be a Christmas gift for my grandchildren, it is still in the boxes. I did peek into the boxes and I think it will be a sturdy piece of equipment. Step 2 always makes quality products so I am not worried. I can't wait to see their faces when they see it!
I gave it a 4 because of it still being in the boxes. I'm unable to make an accurate review at this time.
