Trust me, I don't bias, and don't bs. This is my hobby, the hobby that stick with me from childhood, and is getting more serious as I am more stable in financial and family situation. I am whole heartedly looking and wanting better quality than Zx2, hence I expressed interests into the Mojo as a new technology device, I prayed, and wished....anyways, it is still upon preferences. But why would I keep picking up Zx2 ? I will post my review soon. In the mean time, you can look into my other post.
