I bought a clear pair for night and a dark pair for day use and am extremely pleased. Fit is good and having the clear makes it much easier to see at night on my way home through the two sections of my travel that are dark because of no street lights. The shape does a good job of keeping the wind out of my eyes so I would definitely recommend these to a friend.
There is a difference between something that is low cost and something that is cheap. These glasses are cheap! They broke on my first ride. How? I put them on and the earpiece slid over the outside of my helmet strap (no more than 1/8th" thick) and the ear piece cracked completely!!! The other earpiece also cracked, hairline. There was no force, no jarring action, just cracked. Garbage.
