Review: Durable - Went on a water hike dropped my phone in water about 5 seconds before I got out water, I took case off let dry thinking it would be forever damaged it still works and still has full charge highly recommend this product.
Review: Do not buy this - This is a poor product. The point of failure is the charge point inside the case. It’s too brittle. And when it starts having issues it messes with your phone. You have phantom charging and performance issues and high heat for no reason. Do not buy this product. I want my money back.
