these are pretty sweet. They're super reflective and it's almost impossible to see through them looking in. They're really really dark, so you can't wear them indoors (not sure why you would) and they aren't great for dawn or dusk. But when it's bright out, they're perfect.The only downside is that they do scratch pretty easily. I got 3 because they're cheap and other reviews said they scratch easy, and they definitely do. One of them was scratched when I opened them, although it wasn't that noticeable, but I can see the scratches adding up and being a problem if they get regular use.Good for the money.
