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.

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!

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

Cheap, works as they should.

Easy application

work great. adhesive is very good

Very weak adhesive. Fell off shortly after putting one of a respirator. The only use for this product is in applications where you can be sure the mask won't rub on surfaces in your environment, which completely defeats the purpose of a lens cover - to protect the lens material from abrasion. Disappointing.

Works good
