käntersicher!

An ideal invention for those who already have a good camera, and do not want to invest in a water-compatible!
To use I recommend to practice a little bit before the lens guide not to have the image and placing buttons well.
I was 3 weeks with the kayak in the northern fjords and archipelagos of Norway on the go, the camera is doing very well, even though we are waves gekäntert times in the Atlantic at 5 meters and the camera bag over a good half hour just go in the water .. .. ^^

Shortly:
+++ Absolutely tight! and alongside buoyant (depending on the proportion of air in the bag)
++ Lens stabilization works and can be (on land ^^) open for easy cleaning or to push air out of the bag
To reach all the buttons + good just turning buttons are a bit tricky to use
+ Only slight scratches on the film over the screen, after 3 weeks kayaking and salt water, so heavy use.
+ - Price is not cheap, but attached. I had a more favorable model (Somikon underwater camera bag XL with lens guide Ø 55 mm) ordered for comparison, but I decided against the pocket of Somikon for the not so permanently acting closure. In my 400 camera, it is worth it to me the difference in price.
- The only drawback is the flip side of tightness, with heat or moisture can settle in the bag a little condensation moisture, which was entered when packing the camera. I just had a packet of silica gel (from the original packaging) eliminates having in his pocket, problem.

!! It is important to find the right size for these bags, so pay attention to dimensions.

Zusatztip: I recommend to have a microfiber cloth within reach to wipe splashes
