Functionality is as advertised, but still buggy	I use DSLR controller via wifi on a 6D. During operation varying function such as aperture control, white balance, etc would cease to react irreproducably. Timed bulb exposure (being the only advantage over Canon's own app and the reason why I bought the app) causes the app and the camera (!) to crash. Disappointing and expensive. I keep hoping for more reliable updates.
