Here the assembly was quite fiddly, on the circuit, Handsfree balance and quasi simulate a third hand with the armpits is not an easy installation. But if the part is only even think about it, it works fine.
Distance are around 5-7m. For ideal me, all I have really wanted anyway. However, anyone who wants to use the 12m, which are specified by Steinel, who will probably be disappointed.
Thus arise for assembly and compliance with technical specifications two star deduction.
The pure functionality, especially the price / performance ratio should hold the part again nearly a decade, I will give the three stars.
