Barco ClickShare Tray and 2 ClickShare Buttons, Value Pack — Stylish Tray for a Clutter-Free Meeting Room, USB-A Buttons for ClickShare Wireless Display Presentation Systems, Video Conferencing System

If you have a BArco system at work and you need a few more (plus the tray) this is a good purchase. Once paired, it will work as smoothly and quickly as you current ClickSHare transmitter. You can't transmit 2 screen at once but at least you don't have to pass the button around the table and wait for the boot time (even though it is somewhat short). EVeryone who will be presenting is up and ready and one click off for one laptop and one click on for another.

Excellent

This product works great, easy to sync. to my existing system.

Worked great, once paired.
