This $7 Waterproof Phone Case Has Over 30,000 Rave Amazon Reviews

We bring our cell phones with us wherever we go — even to the pool, the beach, and on boats, which puts our pricey devices at risk for water damage. While a traditional phone case just prevents scratches and cracks, a waterproof case helps keep your phone covered against unexpected rain, spills, and splashes. Although some cases may advertise as waterproof, the tech pros at the Good Housekeeping Institute Media and Tech Lab explain what to look for when buying a waterproof phone case that'll actually protect your device:

• Weather-resistance rating: Look for an IP (Ingress Protection) rating of at least IP67. These are standards around durability. The first number is for solids like dust, the second for water. Solids are measured 0-6, water 0-9, so IP67 would be a good rating for a rugged water-exposed device. A rating of IP67 means the device can be submerged in water up to a meter for 30 minutes. An IPX8 score means the case is able to withstand deeper depths of water where there's more pressure on the device. A rating of 9 would mean it can protect against jet sprays or other high pressure cleaning procedures, which is why waterproof cases rarely have this rating. In short: Look for an IP rating with a second number of 7 or 8 for optimal waterproofness.
• Size: Waterproof cases often add more bulk than a typical case due to added protection. In recent years, we are seeing more streamlined, not super bulky ones that can still offer great protection. When buying a case, always make sure to opt for a case designed for your specific model of phone to ensure a proper seal and fit.
• Extra features: While the main goal of water-resistant cases is to keep your phone protected, they can offer other helpful features. Look out for easy to press buttons and the ability to float to prevent losing your phone during water activities.
