Thunderbolt 3 Mini Dock (HDMI 2.0) - Portable, Bus Powered, 40Gbs, Dual 4K @ 60Hz, USB 3.0 & 2.0, GbE LAN. Compatible Thunderbolt 3 Mac and PC (Dual HDMI 2.0)

I was worried about whether this would work or not. I had a Dell Laptop with a traditional docking station but have upgraded laptops and wanted to connect 2x 1080p monitors, webcam, ethernet and keyboard to my Thunderbolt 3 port on my laptop to have a one connection docking solution for working at home. It does work perfectly, I have the 2 HDMI port model and use a converter cable to DVI for my old monitors and the image quality it just as good as a direct connection. The 720p webcam works perfectly when connect to one of the USB ports. Ethernet port performs at gigabit speeds when tested. The big let down is the length of the cable, it makes it a tight fit and the plug is strained and the cable bent at a right angle. The 15 cm cable is just not enough, needs to be 25cm to give some extra flexibility. Lost a star for this. EDIT: I had problems with my webcam freezing occasionally while using it. The only solution to this was to download the webcam driver for the TS3 model, this cured the problem and it work perfectly now. The support on the CallDigit website doesn't mention this as a solution for this model. EDIT: Updated to 5 stars this has worked perfectly now for last 7 months and has been brilliant for home working.

After purchasing two 27" 4k monitors I was struggling to find a dock that could handle them. After going through multiple options and thinking I will probably have to sacrifice both thunderbolt ports on the macbook pro to drive them, I finally tried this one out and it works perfectly at 60hz. The additional benefits are that it has ethernet and a usb 2.0 port which unlike the usb 3.0 ports doesn't screw up the logitech mouse receiver. So if you have a 2017 MBP 13" and are looking for a great little dock, give this a go. The only thing I would improve is to have power passthrough.

Works great for Mac but it is terrible for windows as it only detects one monitor. Do not recommend

Use it with my 2021 MacBook Pro. Does the job brilliantly. Would have preferred the USB A ports either at 3.1 or 3.2. as then it would be future proofed. Does not get very hot like other powered USB hubs. The RJ45 port works well with Gigabit internet - so does what it says. Thunderbolt is verified Thunderbolt. The Mac tells you when other hubs who claim thunderbolt 3 compatibility is not the real deal. Worth the extra- perhaps if like me you have the need to plug in USB A ports plus RJ45 and an extra Thunderbolt 3 port.

The marketing material on the amazon page doesn't mention that the device will not support dual display on an any Apple M1 / M2 Mac, the page with this information can be found on the CalDigit product web page, where it has a grid showing that only a single display is supported from these devices. Works great if you only want one display connected and the additional usb / ethernet ports. There are cheaper solutions for this though.

I don't often write reviews but it took me a while to find this product so I thought if other people were in the same boat as me, this might be useful to them. I have an 2019 27" iMac with a Fusion drive which is basically incredibly slow, having bought an external SSD to boot from to fix the issue, I lost one of my Thunderbolt slots. This little hub plugs into the other Thunderbolt 3 port and gives me two HDMI slots. I can now run my two extra monitors again. It might sound a bit OTT to have so much screen real estate but as a graphic designer I find it really useful to have one with Slack/Teams/email, my main screen has Illustrator/Photoshop/Indesign and the other has all the palettes and sometimes reference docs like Excel and Word. Anyway it works and although pricey, is cheaper than buying new monitors which could daisychain together.

Purchased to use with my new MBP and enable me to hook up 2 x 4K 60Hz monitors plus all accessories with having to plug into one port, at this it works well. The only flaw with this device is the short cable length, Thunderbolt supports up to 1.0m cable length so I purchased a 0.5m extender to hide this under my desk. The body is made from metal which is nice as I thought it was going to be plastic.

Use with a Macbook Pro and HP EliteBook 850 G5 and works perfectly with both computers to drive two 1080p displays along with the internal displays. There is no power pass through which is unfortunate but wan't a deal breaker for me as the HP unit has its own power supply and the Mac has multiple TB ports so I can use one of the others.

really disappointed considering the price and time it lasted!!!!
