Pocket car window breakers are highly effective for breaking tempered glass side windows, requiring minimal force due to their small contact area. While these tools can work on tinted windows, their effectiveness may vary based on the type of tint used. Concerns about the reliability of spring-based models have led some users to prefer manual tools without moving parts, as they can be more dependable in emergencies. Mythbusters confirmed the effectiveness of these devices, demonstrating that they can shatter windows more easily than traditional methods like kicking or using a hammer. Overall, having a reliable window breaker in a vehicle is crucial for safety in emergencies, especially in scenarios involving water immersion.

I think this stretches my skepticism to breaking.
I will put my money on 'fake' until convinced otherwise.

I used the wildcard "salt window break" in youtube…



So how does the salt break the tempered car side window? By molecular action?

I'd say by spitting a piece of hardened porcelain into his hand before throwing.
