QZQ 30 Pack Peel Off Lens Cover Compatible for 3M 6885, 6000, 6700, 6800, 6900 Series, Faceshield Cover

Fits and works well on the 3M Chinese clones you can get here on Amazon. It has adequate adhesive but I think some people who are complaining about it are missing an important thing here - I think they're not noticing that the adhesive is only on the very edges and you need to peel off the white protective film to use it. It does not stick to the entire lens, only to the sides of it, which is what you need in order to protect the lens from getting any adhesive goop in the area you actually look through. The first picture is weirdly convex which is not what the product is. Not sure why they have that there and it would make you think it's not compatible with the respirator - it's actually flat like it's supposed to be.

I really like these. They protect the lens nicely and I find a little masking tape along the edges to hold them in place helps a lot.

Clear does the job but does not stick as well as i like.

Works pretty good. Just air spray with water and air dry if you need a new one, peel it off and the new cover sticks on by static

These work great! I bought them to protect my mask while sandblasting, otherwise the sand ruins the shield right away. I switch them out fairly frequently, but that’s usually a result of sand getting between the protector and the shield, which I expected. They stayed attached to the shield very well, I never had one fall off. They were easy to see through, and I thought they were a fair price for such a large pack!
