CalDigitThunderbolt 4 Element Hub - 4X USB4 Ports, USB 3.2 Gen2 10Gb/s, Single 8K or Dual 4K Displays, 60W Charging, 0.8m Cable

Update: Working perfectly again. I contacted Caldigit, and they provided me with a set of steps to try (see below). Shutting everything down and plugging in one thing at a time worked. I am also using an Astro "Luna Display" dongle in one of the two ports to allow me to use my old iMac 27. I have a feeling that is the culprit. It can be buggy. But it works now, so I am back to 5 stars. I'll paste their suggestions at the end of the review in case someone else has this problem.Original review:This worked well for two years with my 2020 M1 MacBook Air. Now it’s dead. I’ve tried new Thunderbolt cables and it is passing through the charging but it is not functioning as a hub for drives and Ethernet adapters. My cheaper hub still works.Caldigit sent the following:Thank you for contacting us. We're sorry to hear you're experiencing issues with the Element Hub.Can you please confirm you're using the CalDigit Thunderbolt cable that came with the dock, and have it connected to the correct port on the Element Hub labelled [Computer]?. If possible, and you have access to one, please try a different Thunderbolt 3, 4 or 5 cable (NOT USB-C). Can you please try connecting the Element Hub to all the ports on your system (if it has multiple Thunderbolt ports) to see if the results are the same?. We would also recommend trying a different system and see if the result can be duplicated that way as well.Along with the above, we would also highly recommend that you power cycle both the dock and your Mac. To do so, please do the following in order:Unplug both the Thunderbolt cable and power adapter from your CalDigit device and remove ALL devices attached to the CalDigit device (Thunderbolt, USB, Monitor, Audio and Ethernet).Fully shutdown the Mac (NOT a restart or put it to sleep) and leave it for 60 - 75 secondsPower back up the Mac and once loaded, log into it.After the Mac has been logged into and finished loading, plug both the Thunderbolt cable and power adapter back into your CalDigit device and approve the connection.Once the above has been done, re-attach each device and make sure to do it one at a time and approve the connection where necessary / when the pop-up from MacOS occurs.Regards,CalDigit EU Support

If you need more ports, the Caldigit Express Thunderbolt 4 hub is a very good solution. Since it has its own power supply, it also solves a potential issue with too many peripherals attached to a Mac Studio’s ports causing intermittent disconnects. I had this problem with an external NVME SSD enclosure, and adding this hub solved the problem. My setup successfully recovered from two power outages, powering back up and reconnecting to all my monitors and peripherals. Note, my setup also runs on a UPS to ensure proper shutdown and restart of my computer.

I’m using with a Macbook Air M3 and it works really well. Using with a 27” 4K monitor, audio interface, SSDs, and card readers. and I have a powered 10 port USB hub attached as well.No issues. Just don’t overload it and try to pull too much power from it from things that are bus powered.

I searched for some time for exactly my need and this Caldigit fits the bill. My MBP lacks USB-A ports completely and I'm using one of three USB-C ports for my ethernet connection, leaving only two ports. I didn't need all the extra ports that seem to populate today's hubs and docks. Finally my path crossed the Caldigit Thunderbolt Hub with three upstream USB-C (Thunderbolt) ports and four USB-A port (and no unneeded ports), just what I had been seeking. It works great even supplying PD charging via one of my MBP's Thunderbolt ports. And it looks great, matching my computer's look.

Seems to work well within certain boundaries. I have it connected to a macbook pro M4 with an external thunderbolt display. I wanted to connect two macbook laptops for high speed transfers. Works well with only one downstream mac. When I connect the second the first one loses it's connection to the thunderbolt hub from a networking perspective.I don't know if that's a shortcoming of the hub or the thunderbolt architecture itself. The hub does seem to run a bit hot though I don't know why. My macbook is drawing power from a wall wart so no idea why it's run so warm.

This dock is expensive, but it works flawlessly. I tried a Cable Matters and Belkin dock before this, but ran into weird issues with both that made me return them.The only limitation I've ran into is hitting the ceiling of what thunderbolt 4 on Mac is able to handle. Currently, I run 4k 120hz + 2k 60hz monitors without issue. I wasn't able to set my 2k monitor to 120hz, since I ran into stability issues, but that's a Mac problem.

Purchased this unit to extend two monitors on a 2019 MBP 16" running Sequoia 15.4 currently running a single monitor. Experiencing strange intermittent color issues with one monitor while both are connected, one seems to drop to 256 colors. Also intermittently, one of the monitors will drop out as if it is going to sleep. Switched to a single monitor, color issue went away, but dropout issue still persists. swapped monitors, same issue. tried various resolutions on both monitors, still drops out. I have to reset the cable between the unit and my MBP to regain the connection each time. Sometimes it will work fine for hours, sometimes it will dropout within a few minutes. By dropout I mean the display will go blank and will cycle through the inputs looking for a valid source to connect to. The displays (monitors) I am using are fine. Never had any issues with them prior to connecting the CalDigit unit. I purchased it due to the good reviews and it was offered next day delivery. This could just be a bad unit, but I am going to look for a proper thunderbolt multi-display unit. I would send this back, but I believe I've exceeded the return date. For reference I'm using a 2019 MBP 16" running macos 15.4, 1 LG SQ700s, and 2 Acer EDA320Q-P displays with HDMI to USB-C cables.
