Needed two readers for two PC's. Could not decide on the IOGear 56-in-1 or the Kingston Media Reader. Both about the same price and with mostly good reviews. So, I bought both.
Both do the job, but the IOGear is better.
Why: IOGear is a simple design with easy access ports and a mini-USB port (cable supplied). Kingston has a silly sliding insert design that serves no benefit and a VERY short, near useless, full-size USB cable built in (comes with extension). IOGear comes with very useful little download application that labels each port as to card type in Explorer. No such application with the Kingston. Both are essentially the same size. In principle, the IOGear handles more card types, but that may just be a type-counting difference.
Both work well, but the IOGEAR is a more polished design at same price.
