These work great. I saw just a couple reviews saying they are counterfeit but this is not true. They are ISO certified and this company is listed on the American Astronomical Society's website as an approved and safe Importer/Dealer of known approved manufacturers.
I see some people received some that had manufacturing or packaging issues, but common sense dictates those are isolated incidents given the number of great reviews.
We have solar telescopes setup for tomorrows full eclipse and are hosting a eclipse party. We've been using these to help setup out equipment and test out in advance as well as let family, friends, and neighbors view the sun safely.
Always check glasses for tears, holes, scratches, etc. For getting 10 of these in a pack, for the low price, it's a great deal. We have more than we need just incase some are damaged.
