A helmet's job is to absorb the impact rather than your head. A broken/shattered helmet is actually a good sign. It means it worked.
The Maze is an In-Mold helmet, rather than an ABS shell on EPS foam (like the Holt). Both designs have the same safety and offer the same protection. You are paying more for In-Mold because it is lighter and lower profile while still offering the same safety as ABS + EPS.
