This review is from: Bigjigs Rail BJT050 High Level Track Expansion Pack (Toy)
My first attempt to build this with my son left me wishing I'd paid more heed to the reviews that said it was flimsy, but with a bit of persistence, I discovered that if you wedge the track into the 'teeth' of the support with a little bit of force, it grips beautifully. The resulting construction has been strong enough to move across the room in one piece without falling apart. Admittedly my three-year-old wouldn't be able to assemble it by himself, but with a bit of adult assistance it's perfectly possible to create quite a sturdy spiral from this set and he's loved watching his battery trains going round it.
