What to know before buying

Listing details to confirm

The listing’s compatibility details conflict: its title and model specify iPhone 17 Pro Max, while other details also name iPhone 18 Pro Max. The stated waterproof protection is not consistent with customer reports of water entering around the charging port. The listed weight is 1 Ounces, while feature copy says 1.1 oz. Confirm the exact phone fit and water-use limits before relying on those claims.

Customer feedback highlights positive impressions of quality, protection and secure fit, with reports that Face ID works well. Experiences with water resistance and value are mixed, and some customers report water entering around the charging port. Reports of muffled sound and difficulty hearing during calls matter if call clarity is important. These concerns are especially relevant because the listing claims waterproofing and built-in screen protection, but customer experience does not establish those claims as guaranteed performance.

Positive themes

Customers describe the case as high quality and protective. Feedback also includes a report of flawless Face ID performance.

Negative themes

Some customers report muffled sound and difficulty hearing during calls.

Mixed feedback

Feedback differs on water resistance, with reports of water entering around the charging port despite other customers considering the case fully waterproof.
Customers disagree about value for money and whether the fit feels secure.
