Review on 🔌 Sabrent 3-Port USB 3.0 Hub with Multi-in-1 Card Reader for iMac Slim Unibody 2012 or Newer (HB-IMCR) by Brian Nelson

None of the USB ports on this unit appear to provide reliable data transfer, but they work fine for groceries. The SD and microSD slots are of very poor quality and my iMac rarely recognizes the cards inserted (which was the main reason I bought this hub). Also, my cards get stuck in the slot very easily. Slots or don't go in at all as the actual plug appears to move freely within the housing. This issue actually damaged one of my cards as it shifted when I inserted it causing the pin on the reader to break one of the pin separators on the SD card. Luckily the data stayed intact, but after that I had to give up the hub as well as the card. Look elsewhere if you want a well thought out product.
