Editing Keyboard: Who has one? Reviews?

I would like to know from those that have an editing keyboard, what are your thoughts, opinions and caveats for someone who is considering buying one.
Does it work well? is it quirky? Does it speed up your workflow considerably?
I am considering 4 Resolve workstations equipped with these keyboards. I'd like to know if they would be worth $4K for 4 of them.

Thanks for your input, insights and opinions.

As far as I know it hasn't been released yet; the latest release date I've seen is for "September 2019," which is this month but all the online stores I've checked say it's available for preorder.

The Blackmagic one is out of my price range, but I may end up getting an EditorsKeys keyboard when my current keyboard breaks. It would not have a jog wheel, but I would use it more as a shortcut cheat sheet.

I posted this a year ago... just wondering if anyone actually purchased and is using the BMD Editors Keyboard? If so, what about a review?thoughts? Is it worth $1,000 ?
