Sirui, who or what is Sirui

I've never heard of Sirui, have me but not really engaged in the brand. After this mark, I now heard in various test, I've chosen this head, the G-20.
Why he should be properly processed, not be too expensive and not too heavy, he should hold my Canon EOS 60D with my lenses, Canon 55-250 mm at the time (the heaviest) safely.
All this is guaranteed with the Sirui G-20.
I do not want to go into the big opportunities, friction control and so on, let everyone decide for himself if he needs something.
Here at Sirui G-20 is everything what I need, Panorama Scala with locking knob, and button Friktionsknopf to head fixed points. Furthermore an included removable disk in Lieferumpfang.
Here are some data:
* Material: Aluminum
* Height: 98mm - Weight: 400g
* Load capacity: 20kg
* Ball diameter: 36mm
* Delivery: SIRUI G20 Ball head, quick release plate, transport bag

The load capacity is given as 20 kg, which every manufacturer so slightly exaggerating, but even at 10 Kg I still have enough room. My Canon EOS 60D it considers in any case Bombenfest, also with an attached Canon 55-250 mm I could transport shouldered my tripod with extended legs and mounted camera without the head tipped over.

For me, a strong buy recommendation.
