I tried the Black ones with a blue lens and a green lens
The two lenses it comes with cover a decent range of conditions, but unfortunately they aren't great for lowlight/night skiing. The range they do cover is pretty much slightly overcast to blindingly sunny though. The happy lens technology is quite sweet, with added contrast (don't ask me how they did this, I don't really know) for flat light and adjustable conditions. I found myself using the blue lens a lot more as it was more of an everyday sort of lens. The field of view is huge, probably the biggest I've used without bordering on the obtrusive territory.
The Goggles are made up of some sort of plastic, which is pretty flexible, but after a month of riding I have a crack in the frame which led to a bit of an airflow intake in the lens as it pokes out from the frame a bit/isn't a snug fit. Outside of that, the goggles are holding up well (no ripping in foam or straps), but it's a bit of a bummer about the crack.
Comfort/Easiness of use
These are super comfortable, lightweight, and the most convenient goggles to change lenses with, you literally press and pull a bit and the lenses pop right off. Never had a problem with them coming out on bails, or had to spend more than 5 seconds to swap lenses. Really ingenious system haha.
Spy's definitely on the come up, and these goggles are no slackers. I'd definitely recommend the spy line to anyone (for those with smaller faces, grab the bravo). I had a few minor issues with fogging, but I think those were in part due to my having the strap too loose. Otherwise, I'd give the goggle a 9/10
