I have ordered this wireless connection to my Canon 70D in Photecs because he also does the whole flash process for 2 euros extra. So only charge the battery, plug it into the camera and access the app on the phone. Works flawlessly. In 70D is the advantage (compared with in-camera WiFi), it also works with video. Set camera on the upper floor and added to the kitchen with the mobile phone pictures and videos below. Perfect.
PS: Without naming names, it is good to compare what others charge for the flash process. The same is true for several packets with the brackets thereto. I bought the same brackets in Photecs much cheaper.
