"A purely cosmetic case posing as serious protection for ten dollars."
The 'Military-Grade Shockproof' claim means the flexible TPU plastic might absorb a minor corner drop, but it is not a certification and provides none of the protection of a genuinely ruggedized case.
This is a valid choice for someone prioritizing decoration over protection for an older iPhone. If the goal is to prevent scratches and add some visual flair for a very low cost, it serves that purpose.
Anyone who is clumsy or needs real drop protection should look elsewhere. The marketing overstates its capabilities; a case from a brand specializing in protection will be a better investment.
