Have bought the product because it automatically "customers also bought ...." in the Amazon recommendations appeared. As read in a previous review, the hand strap is too far, there is no adjustment option. I thought that was not a big deal, because my camera while slipping from the wrist would float by the buoyancy the water surface. Unfortunately, the closure is too loose and dissolved often very easy. Namely, in normal - so easy - swimming movements and although the camera was kept in hand. This meant for us no protection against loss in the water. We have audited the closure additionally wrapped several times with adhesive tape. Only through this additional assurance we ventured with our camera into the water. For me, this product does not meet its purpose! I consider it a bad buy!
