Has anyone used VPX Zero carb protein powder?

It has 80 calories, 0 fat, 0 sugar, 0 carbs, is whey protein isolate and 20 g protein. It's double the price I would normally spend so I was wondering if anyone has tried this brand before I run out and buy it and then hate it.

The graham cracker flavor intrigues --

I have not tried it.  

Funny lol. That's the same thing that intrigues me....that and 80 calories. The thing that DOESN'T intrigue me is the $85 price tag at GNC
