Phantom 3 NIR for NDVI

Has anyone used a Phantom 3 with a NIR filter to get good quality NDVI? Or, has anyone had good luck using NDVI on the RGB images?

There are a few posts on the forum of examples:

@aerialmediapros performs the same modification on the Phantom 3 that is found on the Inspire NDVI cameras. The camera resolution is the same on both the P3 and Inspire (12MP), so any data or images that you see on the Inspire NDVI camera are valid representations of the P3 camera.
