iMac Hub Aluminum USB Hub Adapter Docking Station with Micro SD & Micro SD Card Reader Combo and 3 USB 3.0 Port Compatible with 2021 iMac and iMac Pro (Upgrade Version)

Got this to use on my late 2015 iMac and it works perfectly. Absolutely no issues so far, and it helps add more accessible connection ports. Highly recommended, will update if I have any issues.

Not the securest fit

I was looking for CF Card reader because transferring the photos directly from the camera takes so long.I was so happy to find this product. It has 3 USB ports, CF Card Reader and SD and micro SD card reader.The transferring speed is many times faster than using a USB cable from Camera. In additional, it look really cool with my MacBook Pro and wood Ikea table :)

At first once I figure out how to place it in and under the Monitor on my desktop , it took me 10 minutes to place it on , but now it’s great and convenient and easy

I am a wedding photographer and my digital files are of the utmost value because wedding images can never be recreated. I purchased this docking station to make uploading/downloading my camera cards and external drives more convenient - HOWEVER, the big problem is every time I insert an SD card or external drive, it automatically EJECTS any other drives that is already plugged in!! And proceeds to give me the message "Disk Not Ejected Properly". This is extremely dangerous and can result in damaged files, especially while they are in the process of being uploaded. I will not purchase this product again. Too much risk for my business.

This docking station sure makes it easy to plug in USB devices. You do need to hold the bottom of the screen as you plug in. Small price to pay for not having to turn the Mac around.

The device is a great idea. Take note Apple. The problem is that it is very difficult to attach to the iMac. There is not quite enough space in the attachment to get it to hold properly.

Looks great, and works great. It does. It stay out very well though, as it is not possible to tension this enough for the small clips to be able to withstand the forces applied the the port. So use care while inserting and remove cable or memory cards.
