UGREENMac Mini M4 Dock with DisplayPort, 8K@120Hz Max Display, Up to 8TB M.2 NVMe Enclosure, 4x USB-A and 1x USB-C Data ports, 170MB/s SD/TF Card Reader, 3.5mm Audio for Mac Mini M4 / M4 Pro

Connects easily and instantly on my Mac Mini M4. Note that it takes 2 Thuenderbolt slots to connect but the high speed replacements are fine. Mini sits very nicely on top, says it helps with cooling but not tested that - mu Mini doesn't seem to run too hot anyway, fan has never come on. Nice cutaway at the back for access to the Mini's power switch. Comes with a little screwdriver to access the SSD slot - haven't installed one yet, but don't anticipate any issues. Nice bit of kit, well made and finished, matches the Mac perfectly, ports work fadt and effectively and also looks good.

It's exacltly as described. This is a USB hub in a useful shape with lots of bandwidth. It provides some useful ports and gives easier access to the power button, which is exactly what I wanted.I found that the NVME slot worked with a PCIe based drive and this worked the same as a USB pen drive - an icon on the desktop which can be ejected. This doesn't provide a drive linked onto the filesystem.The front USB-A connectors can't provide the power to run an external CD drive, but this is common with other USB hubs - I just use the front panel USB-C sockets with an adapter.I found that the display port wouldn't drive HDMI monitors via display port to HDMI video adapters or cables. These worked with other machines so it's a odd setup issue. I just used another USB-C hub instead.The speed of access and bandwidth provided was certainly fast enough. No complaints here.

I'm a big fan of UGreen products and have purchased quite a few over time. They nearly always nail a good balance between price and performance, and this Mac Mini dock is no exception. I paired it with my base M4 Mac Mini and a Lexar 1Tb NVMe SSD. Build quality is nice and it matches the Mac Mini aesthetic perfectly, with the bonus that it allows access to the stupidly placed Mac power button. I noted no discernible drop in my WiFi speeds with the Mac sitting on top of the dock, and all the extra ports are great.The only con I can mark it down for is that the internal drive slot is limited to 10Gbps, which is a good deal slower than most modern SSDs are capable of. Given that it connects to the Mac using the rear Thunderbolt 4 ports, it's disappointing. It would have been nice to see the full 40Gbps speeds.

Works extremely well with the Mac mini, is very quick on data transfer

Excellent product

Does what it says useful extra storage without using dongles blends in with mac mini extra ports and with USB a and SD card slot, i find it does affect WIFI a little but not much for meas my router about 8 feet away from it but does knock down 100-200mb/s

Waists 2 usbc ports, needs more usbc ports than usba,b ports, such a shame needed a extra hub to gain usbc ports

There are some nice highs on this dock, primarily the expansion port it contains to increase your Mac's storage capacity, ideal for supporting you on storing large volumes of videos, images and movies via an M2.NVMe SSD, ranging from 2230 to 2280 and up to 8TB capacity.A single cable interconnects to your Mac allowing you additional ports including a Display Port, which when combined with the existing HDMI port, allows you to have 2 monitors.The lows on this is that there is a USB C port on the rear, but this doesn't offer video capability, a feature that would have been very useful.If you're not too bothered about how you connect your display cables, but just want to have that small edge on your existing Mac Mini M4, then this will the job nicely, but you may be able to find similar docks that may offer additional features, such as dual Display Port or video output on USB C ports.I do like the overall design where you insert both SD and Trans Flash (mini SD) cards at the front of the dock, a much tidier way of connecting rather using these hub designed units that with need to be plugged into a USB A port and/or slide about the desk, this dock simply does keep the workspace clean and tidy.
