Underwater Waterproof Case for Cricket Debut Smart/S3/S2
Skip. Waterproof cases often use PFAS-based water-repellent coating coatings; unspecified coating raises concern.
This underwater case likely uses a waterproof coating, probably water-repellent coating-treated polymer, but Dexcraft discloses nothing about PFAS content or materials. Waterproof phone cases commonly contain PFAS in their protective coatings.

The full breakdown
What it's made of and why it matters
This is a rigid plastic protective case (material type unspecified by manufacturer, likely polycarbonate or ABS) with an applied waterproof coating. The coating composition is not disclosed, which is the primary concern: waterproof cases typically use either PFAS-based water-repellent coating (water-repellent coating) treatments or silicone-based alternatives. Without clarity, you cannot rule out legacy PFAS chemistries. The plastic housing itself may include UV stabilizers or plasticizers that can migrate under prolonged sun exposure or thermal stress.
The brand's record and disclosure
Dexcraft has no published material safety data sheets, chemical disclosures, or certifications (e.g., bluesign, GOTS, OEKO-TEX) for this product line. The brand maintains silence on coating composition and flame retardant use, which is standard for budget protective cases but limits your ability to make an informed choice. No recalls or reported incidents specific to this case are on record, but absence of reporting does not indicate absence of risk in unregulated product categories.
How it compares in its category
Waterproof cases for wearables exist across a wide price spectrum. Budget options (under USD 20) almost universally use undisclosed coatings; mid-range alternatives from brands like OtterBox or Spigen sometimes publish material lists, though few guarantee PFAS-free formulations. This Dexcraft case sits at the budget end with zero transparency, making it harder to differentiate from competitors using known PFAS chemistries. If PFAS avoidance is a priority, cases from manufacturers with explicit non-fluorinated coating claims are preferable.
If you buy it
Store the case in a cool, dry location away from direct UV light, as prolonged sun exposure accelerates plastic degradation and potential leaching of additives. Do not leave it in a sealed hot car or expose it to temperatures above 65C (150F), as waterproof coatings can degrade and off-gas in heat. Inspect the seals annually for cracks or peeling; once the waterproof layer fails, the case loses function and should be replaced rather than repaired. Hand-wash with cool water and mild soap if needed; avoid solvents or high-pressure cleaning.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Waterproof coating composition (unspecified)
Manufacturer does not disclose whether water-repellent coating uses PFAS, silicone, wax, or hybrid chemistry. Unspecified coatings on waterproof gear frequently contain legacy PFAS fluorochemicals or newer fluorine-free alternatives; this case provides no way to distinguish.
Plastic leaching under thermal/UV stress
Polycarbonate and ABS housings can release bisphenol A (BPA) and other additives when exposed to sustained heat, UV radiation, or contact with certain solvents. Risk increases if case is left in sunlight for extended periods.
Coating degradation and microplastic shedding
Over 1-2 years of use, waterproof coatings can peel, crack, or flake, creating small plastic fragments that contact skin or the wearable. No test data available for this specific product, but common in budget protective cases.
Seal integrity and bacterial/fungal growth
If seals fail or water enters the case, trapped moisture can support mold and bacteria growth inside the sealed chamber, creating biofilm near your wrist. Regular inspection and rapid drying after water exposure reduce this risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
