Keeps really tight

Although initially had some concerns, but this Case holds really tight. Have made and photos taken a few small dives and took it every day for swimming. Better than letting unattended on the beach;)
However, it must be enough air in the case that the touch screen can be operated under water! In addition, quite a few have mentioned the problem with the seam. Which also makes me the buttons on the side and the lock button can be pressed hard.
For those who have a problem rauszubekommen the unit then, following trick: Just looking purely blow strongly into the case so that it inflates, then slipped the phone out almost by itself. Works for me every time.
Great product, I can really only recommend it!
