1. The reason for the purchase was the fact that underwater housing cost more than EUR 1000. So this was an inexpensive alternative.
2. It was my plan to go diving with it, not only snorkeling. This also works great. It is very important but that sucks so much air as possible from the DicPac, I did it with a jam sucker. The first dive worked well because the very air from the DicPac was. The Bildqulität was also very good. I did it for safety's sake but with "Ducttape" sealed to ensure that there are no leaks.
3. Conclusion: The DicPac works very well when all the air sucked out of the Pac. This is very important. I have not sucked the air in my 2nd dive out and it did not work. I was deeply up to 25 meters and it has made great pictures. At the 2nd dive was unfortunately as I said too much air in DicPac and it did not work because the air was compressed and the camera has become undbedienbar. I highly recommend this very DicPac. You have as I said good care that all the air from the DicPac is. Also, I would never be a camera which is worth more than 100 EUR use. I have an old small DSLR with a 50mm 1: (bid for 60 EUR on eBay The lens I had.) 1.8 used since one underwater light has less need a fast lens if you really want to go diving.
Really very good and as I said, the air must be out otherwise it is useless. And to be sure I tight it from always with fabric tape.
