Everything on the shield works great, and looks even better.
I was able to use this shield both at night and during the day with no sunglasses during the day and no real problems riding at night on well-lit streets, which was really convenient. Visibility was great, make no mistake.
However, the mirror finish scratches really really easily so you have to be careful when handling this face shield, and avoid letting bugs hit your shield front and center cause that will scratch the finish and probably annoy you while riding.
If you have the money, get this shield, but be sure to remember that these are more or less disposable items.
The adjustment over the bridge of your nose is far enough down that if you tighten it enough to really seal, you'll plug your nostrils. Allows me to ride just fine, though. I don't fog my shield with it, just the glasses if I don't watch my breathing.
Installation's a breeze. just pull 2 snaps.
