The Freedom Mini Duo is an incredibly light portable keyboard for the Smartphone or Pocket PC. It weighs in at a mere 83 grams (3 ounces) and is approximately as thick as a credit card. The keyboard itself has 62 keys laid out in a membrane design, requiring the user to add more pressure when typing to register the key they’ve pressed. Freedom used this design mainly to keep the keyboard lightweight, and they’ve also designed the keys to be as close together as possible. This makes the keyboard feel a bit cramped, making it challenging for users who have big fingers or need more typing space. However, the spaces between the keys and the need for more typing pressure are simply tradeoffs to the portability of this compact keyboard. The bundled rechargeable battery is long-lasting and offers 9 hours of continuous operation. In a roundup of portable Bluetooth keyboards, the Freedom Mini Duo was the most economical choice.
