MacRumors published a review on the Kingston Nucleum USB-C Hub
A quote from the article:

Kingston's Nucleum USB Type-C Hub is designed to meet that need, offering a selection of useful ports for MacBook, MacBook Pro, and iMac owners who still need to use the USB-A, HDMI, SD, and microSD ports that are no longer available on recent machines.
