- I got one of these sets like four years ago. They're pretty cool,
- the only problems I've encountered are the sliding of the balls. You'll
- set up a hill, and the balls will go down, but will not be able to make it
- UP the next hill because of backspin imparted on the balls. The only
- other problem I've seen is the inablilty to build anything realistic.
- You can't build a scaled down model of The Magnum. You can't build up
- enough speed in order to accomplish this. BUT you can make rides that
- go through 5 consecutive loops =) . Maybe they've improved it since then.
-
- My advice, BUY THE BIGGEST SET, it's the only way to build the best stuff.
