This looks nice, for sure. The Hub+ is more my style, though. I hate the USB DisplayLink adaptors. There's always lag, and every time there's an OS update, there seem to be driver issues with them. Plus, how many people actually really want to run 3 displays from their rMB? If someone says "I do" well then you should definitely back this Kickstarter! But I don't think most do.
It has its own power source. I understand the benefits of this, but for me, I'd rather utilize the USB-C power passthrough.
All in all, I agree with the comments that this will likely be a high quality dock, as the company has a history of delivering good products. Furthermore, the fact that it has its own 60W power supply, the displaylink adaptors, etc, makes me think that this will be broadly compatible with other laptops out there other than the MacBook.
So yeah - looks like a quality product - not the product for me though.
