Bests & Worsts Reviews from Amazon

I bought this lens to replace a Bionic Shield lens that literally saved my life. I had a kickback on a table saw while cutting 2" thick oak. I had just started wearing the Bionic Shield when cutting on the table saw because it kept sawdust out of my face. Thank God I did that because the 4lb piece of oak hit me right in the mouth. I suffered a split lip but I could have died and at the very least I would have broke my front teeth and probably my jaw. The lens did not break! The force of the blow pushed the entire face shield into my face but the force was greatly reduced. I can't say enough good things about this face shield. I use it 100% of the time while I am turning wood on my lathe. I wear it for hours at a time and it's comfortable and fog free.
