I bought some of the problem glasses on Amazon. They were very dense gas welding goggles, where what was actually needed would have been a plate from an arc welding mask. Arc welding has a much greatter ultraviolet component. At the time I purchsed them, months before the eclipse, they appeared to be the best things available, and I wanted to stay away from the plastic film glasses if possible. I spent about $150 for three.
Only a day or two before I left on a trip that was to lead to viewing the eclipse in Prairie City, Oregon. Amazon wrote me, asking me not to use the glasses, refunding my purchase, and stating that it would not be necessary to send them back. They are still OK as gas welding glasses, I suspect.
We ended up using the film glasses, and various observing devices with filters or projectors. I made a really nifty solar projector out of a telescope I got from a flea market, which the crowd appreciated. It's a lot easier to see the sunspots when the sun is projected a foot wide.
I viewed the total eclipse using unfiltered Orion 70x15 binoculars on a pantograph mount. I saw everything. The planet mercury, solar prominences, etc. I definitely recommend binoculars.
