Got one for Christmas. I attached it and played with it for a few minutes. Seems to do what it says it does, but recognize my limited hands on experience. The videos seem correct that I saw on it to what I messed with. (7D and 1D Mark III)
Interesting, I didn't know it had a wireless mode. I have the trigger trap but only used it a couple times, it's a nice device for its money but I have had a response issue with it, it doesn't fire the camera every time. But I was using a 10' extension on it and that may have been the cause, I didn't really spend any time/effort trying to figure it out
I use it. I've used the wireless mode, the time lapse, the bramp mode, the distance lapse, and star trail mode, and motion detector mode. Pretty good for a simple dongle to iPhones.
