My local pro-shop got them as a prototype awhile ago and got to try them on, etc. He said that for the price they're debatable (if you have money to blow, then blow it basically). But if anyone here is familiar with the DYE i4's, you get even MORE vision. He said that he wished the I4's gave that much FOV.
IMO the best way to buy goggles is to wait until august and kopp last years model for cheap, most goggles look pretty much the same year after year and goggle technology isn't really advancing that fast unless you want a heads up display or built in camera.
