We synchronized via Bluetooth with iphone of my wife (on an iPhone 4).
We used this weekend during our walks with the children.
To use it is simple:
Just turn on the iPhone, put it in photo mode and lay it on the pole.
We must turn the pole, and then you have to press the button and perch the picture is taken. It's really super simple.
At first I was afraid to put the iPhone on the pole but it is well maintained.
I personally do not understand why we had not bought a pole before because it's really convenient.
