Since I could not find a single post on the internet on how to remove the ac vent of the neo, let me share with you on how to do it.
Step 1. Turn the outer ring to make the internal flap open fully. Failing to do this would not enable you to depress the tabs as per Step 2 below.
Step 2. Press on the two tabs located approximately at 4.00 & 8.00 o'clock at the rear of the vents. (Picture below)
Step 3. While holding down the tabs, gently but firmly pull the vents out.
