I belong to the Amazon Vine review group and have access to products that require an honest review.  This product was sent to me to review.  I was able to get my phone (iPhone SE) into the case and then immersed it into water to see if it leaked.  It didn't.  Then I repackaged it all and wrote the review.  It has never been used in open water and shows as new.  What you get is a unit that has been tested.
