(Mostly) a top product

I use this adapter for both Olympus and Samsung NX and can recommend it in principle. There is at me a few minor problems, but do not bother me too much in view of the many possibilities of the dongle and the corresponding app.

On my Samsung NX1000 it sometimes comes to freeze the camera, which can be resolved only by the design acquisition of batteries.
With an Olympus E-PL3, it comes, however, when you plug in the cable to the premature release of the camera.

App, you must also install, I can say the following:
On iOS, the app draws a relatively high current and my iPhone 4 is very warm after a short time. If you do not use the screen for a longer time, he dims yes from default. But once you want something again press on the screen and the app has Triggertrap open, then it can happen that the screen is bright again immediately. Then you have to open the back Home menu and the app again. In addition, it is more common that the icon for the volume control appears suddenly, without me having served the volume or low volume button.

On Android, the app works only as far as I could test it without any problems.

The "cool" to the app is that you can tinker a remote release with 2 devices. They can also be Android and iOS devices are mixed. A device is directly wired to the dongle and serves as a slave. The second device is used as a trigger, and sends the signal to the slave. It can be connected to a triggering device, incidentally, several slaves. (The whole can only work if all the devices in the same Wi-Fi network are).

Conclusion:
Can be still working on the implementation of iOS app. The use with Samsung NX is a little limited, but otherwise I give this product my buy recommendation
