It may be possible to buy two 77mm polarizers (for under $20) and achieve the same effect, although I have not tried this (yet!) =).
As opposed to a true ND filter, these are polarizers so you will have the polarizing effect in addition to the ND light-lowering effect, whether you want it or not. Rotating the second filter alows adjustment of the light-blocking level, but since the 1st filter is fixed to the threads, you will have to keep it loose and rotate the WHOLE filter assembly in order to adjust the polarizing effect. This could be tricky if you need to get both effects just right.
The only other issue I found is that the glass is not terribly flat, and I noticed quite a bit of distortion (heatwave effect) as I rotated the entire filter in front of my eye (not mounted to the camera). I have not tested to see if this distortion makes a noticeable difference in the images or not. Some testing is certainly in order.
Overall, this is a neat product, with a few unexpected and potentially useful hitches, but perhaps a bit pricy considering alternative methods (buying two much cheaper polarizers) and the not-so-flat glass used in the product. So there you have it!
Also didn't liked that they didn't specified that the 77mm version actually increases to 82mm, so my 77mm cap doesn't fit. Otherwise I would have bought a 82mm cap together with this.
