Mobile Fidelity Carbon Cartridge?

it has been about a year since this cartridge was announced, yet I don't see any opinions or comments regarding the cartridge. I don't even know of anyone acknowledging that they own one. Is it still available or was it ever?

Does anyone have any experience on this cartridge? I love the Myabi sound and was curious how this cartridge stacks up. Few reviews exist on this cartridge.
check out issue 10 of Tone Audio. It's free and online.
thanks for the link. I had seen that review as well. I am sort of curious why no one steps up and talks about their experiences with the carbon cart. I have to assume that few are being sold.
