“I really don't understand the point of the flexible pieces. I thought they'd allow for a sharper curve, but they really are the same radius as the fixed curve pieces. Combine 4 of the 8 flexible pieces together to get one of the fixed curves. I thought we could make a tighter curve than what a set we previously purchased allowed. Instead all we could do was use the extra straight pieces and a few fixed curves to make a larger "circle". This set is too small and not "flexible" enough to do much of anything when combined with the set that came with my train.”
