Tailored Fit for iPhone 17 Pro Max

The Tech21 EvoCheck case is moulded specifically for the iPhone 17 Pro Max, delivering full coverage with a glossy black finish. Its silicone-gel-rubber construction wraps the handset while keeping MagSafe compatibility intact. The subtle check pattern adds a distinctive look without bulk. It suits owners who want protection that matches the phone's exact contours.

Drop Protection and Self-Healing Surface

FlexShock material absorbs impact energy rated for drops up to 16 feet, while the self-healing outer layer resists everyday scratches and scuffs. Interchangeable mechanical buttons let you refresh the tactile feel when needed. A Bio-Spice additive helps the plastic components break down in landfill conditions, excluding the internal magnets. These features extend the case's usable life.

Raised Bevels and MagSafe-Ready Mounting

Raised beveled edges lift the camera lenses off flat surfaces, reducing direct contact during daily placement. The integrated MagSafe alignment ensures secure attachment to compatible chargers and mounts without removing the case. The flexible silicone-gel-rubber body grips the hand and slides into pockets cleanly. Build quality focuses on precise cut-outs and long-term shape retention.

Questions about this item

Will the self-healing surface still hide scratches after a year of daily pocket carry?

The self-healing material is designed to resist scratches and scuffs continuously, so everyday pocket wear should remain invisible without any extra treatment.

At what drop height does the FlexShock layer stop absorbing impact energy?

FlexShock protection is rated for drops up to 16 feet, so impacts beyond that height are the first limit where the case can no longer guarantee full absorption.

Does the MagSafe ring get hot or drain the iPhone 17 Pro Max battery during all-day wireless charging?

The case adds no active electronics, so it generates no heat of its own and does not draw power from the phone while MagSafe charging runs all day.
