I agree with bonfire that this is nothing newsworthy. It's just another existing MX goggle mold that has been reused to create a DH goggle. In other words, this goggle frame is [I]not[/I] specifically made for MTB. MX helmets are often bigger with different sized and different shaped face openings than DH/Free ride helmets. There are also airflow issues that should be considered. MX is always relatively fast whereas DH and free ride can slow down quite a bit. The decrease in airflow can allow the lenses to fog. My point is that an MX goggle rebadged as a DH goggle is nothing newsworthy because we've seen it a million times before. The price is good though, and for that price we can't expect anything more than a rebadged MX goggle.

Photochromic lenses are good but can be dangerous. They're fine if you're only riding in the alpine or any spot where you won't be entering forest or dark areas. The lenses go from light to dark in about 10 seconds but take a few minutes to lighten back up. If you're riding in and out of trees, they'll go really dark on you but won't have time to lighten back up. The goggles above look like budget, which they are, so there's nothing wrong with that. There's nothing special about them either.
