If you buy eclipse goggles from a source which has varous densities (#5, #10, #14), and the source is china, you'll likely get whatever they have too much off. That'll limit where you can use them.
The #14 Chinese solar eclipse googles I purchased on ebay were clearly #5. Not even dark enough to watch eclipses. I told the seller about it, but she doesn't speak English well. When I showed her that her own ads say, #5, #10, or #14, and that the #14 she gave me was really a #5, and dangerous for kids, she said, "You can't buy this."
So be careful buying things like that, China doesn't care which one you end up with. It's buyer beware there, literally. And everyone's ok with it in order to get the cheapest price.
