"Attack of the card readers! We bring you yet another card reader, this one also has a usb hub in it as well. This card reader and usb hub combo is made by I-Rocks. It's a 12 in 1 usb 2.0 hub reader. I've seen their products here and there but had never bought one or seen first hand, so I decided to read up a little about them on their website. They have been making computer peripherals for over 13 years now and are located in China. I would like to thank I-Rocks for the opportunity to review the “Crystal” Usb 2.0 card reader& hub combo (IR-8100)."
