Blackmagic Design 4K Mini Reviews
Works, but with serious issues

Does this enable you to get a 4K signal into your computer? Yes.
We purchased this because the Magwell 4K Capture devices, although good, were often getting "forgotten" by other software, Like Resolume, in our permanent installations. This was causing issues weekly.
After researching other devices this one came highly recommended.
However, there are some serious drawbacks that had we known them we probably would have not bought it for a permanent installation.
The first is that if you have it connected to your computer, like a Mac M3 Studio, and restart the computer, the computer will not boot to the screen properly. There is a handshake between the device and computer and something to do with the Thunderbolt bus. If you remotely log into the computer you can see it is actually running but the main monitor will show a "no signal". The only fix is to unplug and reconnect the Thunderbolt cable. Not even power cycling does it.
We tried new Thunderbolt cables, new monitor, literally everything. The issue is the Blackmagic Design UltraStudio 4K Mini.
We called support at Blackmagic and they were not very helpful., The first person blamed our HDMI cable (which we already told them we had tried other version of) and the 2nd person said they had never heard of it but would help us via email. Only received 1 reply, haven't heard back in 3 months after following up multiple times.
We tried all the firmware and can confirm this device is causing the issue. It's not the computer, the monitor, etc. This obviously should not happen and is a huge drawback.
The good part is the Resolume is now always connected but the tradeoff is that every time the computer restarts a cable has to be manually unplugged and replugged which is honestly just as bad as the initial issue.
Next, the audio out does not work. The volume knob is either way too fine grained or just does not work sometimes.
You also have to have special drivers to install. The program you get has very few features. Unlike Magewell.
The HDMI loop out does not always work.
Oh, and the very handy reference monitor on the front will not display if the computer software is using it which makes it useless.
Given the price, issues with being connected during restart, and lack of support, this gets 2 stars.
Worth noting is that every single issue here is fixable with software. Given there are maybe only 3 items on the market (Magewell, AJA, and this one) hopefully Blackmagic will eventually fix it via firmware.
Waste of Lots of Money

Could not get my Mac Studio with M1 chips to even find this thing. There is no customer service department at Blackmagicdesign. No number to call. Not even chat.

I don't think much. I spoke with someone from BM and I think they said that it's for a future release or function.
