I had 2 different pins, but had their weaknesses. But the Mumbi is genuine class. It works really well and also on different devices. I tried it on my Samsung Tab 2, Nexus 7, Nexus 4, Lumia 800, ZTE Racer II and Ipad Mini and everywhere he does his job very well. We must press on, what was the case with my predecessors hardly. And the Kulli to round off him great.
