I use the Trend Air Shield Pro since I have developed wood dust sensitivities over the years. I also agree with wolf creek knives about its many attributes. Although somewhat on the expensive side it offers great protection and has a wide field of view. (Just don't use it if applying CA finish as you will not be able to remove it fast enough when it sucks those fumes in :redface
I just purchased the Uvex Bionic Shield (non anti-fog model) for use by visitors when they come over to turn. My son used it for two days and loved it. It is light, and also has a very wide wrap around field of view, unlike the simple face shields often found at the local home centers. The solid frame around the clear shield provides excellent protection.
It didn't fog up for the entire time, but I live in the So Cal desert so that probably played a factor. I wouldn't hesitate to buy the Uvex Bionic shield if I needed another one
