for the long arm

Extendable pole, bluetooth connectivity, immediate recognition of your device to make your selfies but also more rare for this kind of accessory, the possibility of triggering video.
A cord passed around your wrist you avoid unpleasant surprises. Well balanced, this telescopic rod (not telescopic) will allow you to take good pictures and good videos by taking the distance necessary to capture objects.
Very intuitive, no need for chemistry information sheet to make it work. Rechargeable (attached cable), you will for a moment before returning to the load. In short, very interesting product I would have liked rather telescopic qu'extensible, but this is a detail.
