Jimi is a J-shaped extension that eliminates the need to strain to reach the USB port at the back of the iMac.
Simply plug Jimi into the USB port at the back of the iMac and extend the bottom of the “J” to snap into place along the bottom vent of the computer. Jimi is exclusively designed for the iMac Slim Aluminium Unibody model (released November 2012) or later.
Available in the UK for £12.95 from Amazon.
