Just received this today. It looks like a knock-off, which is not terribly surprising. On the other hand, it's a pretty good knock off, so I'll probably go ahead and use it.

care to post some pics of it? interested in obtaining another holder for back up purposes.
+1, how can you tell it's a knock off? I'd love to find a knock off source (for a reduced price)...

Most of the images mention using a 2 or 3 stop Hard/Soft GND filter, I believe Ben uses a CP most of the time as well for his shots so that's an extra 2 stop reduction for the entire image. If I only use a GND filter, say, to shoot a beach and cover up the sky potion to reduce the brightness, wouldn't the uncovered portion of the picture be saturated because they have no light reduction?
short answer: no
long answer: no, because when you use GNDs the dynamic range in the image is so broad, the sky is so much brighter than the foreground you can't capture both at the same camera settings. You'd need one exposure for the foreground then another 2~3 stops shorter for the sky. The filters just makes it work.
Do you stack a normal ND filter on top of the GND/CP filter to not saturate the image?
the CP changes the saturation. NDs change the length of the exposure. GNDs change a portion of the images exposure to "compress" the range enough that a camera can capture it all in a single image. If I need a longer exposure than I'm getting with the CP and GND, I'll add a second GND but shove it all the way in (making it work as if it were a 4x4 ND, I'm too cheap to own both).
