No Case is Tougher: EFM D3O Crystalex Phone Cases Survive 6 Metre Drop

To the best of my knowledge Perth based company EFM’s phone cases made of D3O Crystalex are the toughest available for Australian customers to buy.

A lot of other case makers make claims about being tough and drop proof but I couldn’t find any that beat the drop distance D3O Crystalex promises to survice.

The company claims that they will protect your phone from drops, knocks and shocks from a falling height of up to 6 metres off the ground (military standard drop exceeded by 500%).

The claims seem to be true if you checkout many videos on YouTube of the D30 material being tested in all kinds of scenarios including dropping phones a long way and professional athletes surviving strong impacts.

The special ingredient D3O Crystalex is also used around the world in helmets, gloves and other protective gear by soldiers, professional athletes, industrial workers and motorcyclists.

D3O uses unique patented and proprietary technologies to make rate-sensitive, soft, flexible materials with high shock absorbing properties.

D3O technologies are based on non-Newtonian principles; in its raw form, the material’s molecules flow freely, allowing it to be soft and flexible, but on impact, lock together to dissipate impact energy and reduce transmitted force.

D3O Crystalex impact protection material is completely clear so you can still see the great colours used in modern phone designs. EFM claim that it also has anti-yellowing technology built-in so the case will remain clear for it’s lifetime.

I’ve used an EFM Cayman case (bought from JB Hi-FI for $59.95) on multiple phones including my current one and they have all survived several drops without damaging the phone at all.

The EFM case worked fine with the infinity edge display, wireless charging wasn’t hindered and the case edges are raised around the screen to protect it if it drops face down.

You can buy EFM tough phone cases directly from their website or via retailers like JB Hi-Fi.
