I received the stick as a gift and since now 3 months occasionally in use. Processing acts robust and high quality. With the universal rubberized mount the stick for all common smartphones, even very large models suitable. The operation of the telescopic pole is very fast out of hand. Even compact cameras can be mounted if required via the standard support plate (screw thread). The stick conveys a good sense of security - I would have no qualms about losing the mounted device or damage. Triggering of the photos comes with the easily accessible button also easily by hand.
I've tried to stick with several iPhones and Android phones. Here (iOS 7 and 8, Android 4 and 5) there were no problems when using the standard photo apps. Important: If the phone does not respond, or trigger his lack occupied please always check whether the correct operating system is selected by pressing the button under the trigger. Left (white) is Android, the right (blue) iOS. This statement is missing the way in the user manual provided.
