This kit installs on my MacPro 5.1 in about 20 minutes. I can restore my machine to its original condition at any time. Moving the Bluetooth antenna outside of the MacPro case increased my MacPro's signal strength by about 10dB. This allows me to install a third party USB3.0 card and use newer and faster USB devices in my MacPro. Without this kit, adding a USB stick made Bluetooth unstable. Moving the antenna outside of the case solves this problem. This kit includes an extension cable and velcro/double-sided tape to allow you to place the Bluetooth antenna directly under your mouse and keyboard. I haven't used it.
