This mobile phone case can do moreIt is softly padded all round, which not only provides a certain degree of impact protection, but also keeps the bag buoyant with its contents. 300 grams of buoyancy are stated, the test sample floated safely on the surface with a 5-inch mobile phone.
For the one-hour diving test (although only 10 centimetres deep in water), we had to weigh it down properly, but the inside of the case survived the small home test completely dry. Operation also works with the device in the bag, but not the fingerprint scanner.
Having already sunk a mobile phone together with my car keys (which is now nicely packed in a waterproof case, but at a depth of almost 100 metres), I would pack my mobile phone in such a case with an integrated float for the first time again without hesitation.
And for those for whom mobile phone-free time is important: on the water, the smartphone can also function as a fitness tracker in flight mode (Runtastic, sports tracker, etc.), which tracks distance, speed and route and serves as an aid if you are in need...
Conclusion: If a mobile phone case, then it should be floatable. The test sample was convincing, but the price is quite high in comparison.
Price for the test sample: 19.90 (offer price) to 35.90
Top: Apparently properly sealed, still floats even with contents, comes with safety strap and carabiner
Well: Closure is not particularly ergonomic to open
Bad: Nothing
