In the other reviews here Delivery and handling were already described in detail, so I refrain at this point unnecessary repetition. Shortcut: The Stick-Charging, clamp the cell phone in the holder devices pairing to trigger photo by pressing the button on the stick. Works well and also works as easy as it sounds.
I think this drive is particularly suitable for entry for all who want to try this different way of photographing once and test new perspectives. If you want to use as an extended arm regularly and for serious applications, on the other hand probably attack sooner or later likely to a higher-value model. The functionality is given though full, but HighTech one must for this price do not expect realistically. A nice gimmick is the stick but in any case and as the price remains limited also suitable as a small gift.
Finally, my thanks to the producer of the provided test pattern, however, associated with the request in future be enclosed with the product in addition to the English and a German manual. If you offer this product on Amazon.com, this was supposed to be self-evident.
