At the very best there is great difficulty trying to reproduce the results reliably. It smacks of amateur hour. Maybe some scientist in some lab will be able to puzzle out the secret, and then cold fusion really will be ready for prime time. But this just does not look like 99.9999 of modern technical success stories, which were pursued in labs.
Back shortly after Pons and Fleishman published their experiment, a physicist in Palo Alto California decided to pack their recipe in an air tight metal cylinder.
The result exploded violently, killing the physicist, and completely destroying his laboratory. There was no follow-up ever reported on it.

That's a broken record that's been playing since 1989. I'm not so sure the results can't be replicated today.
Note in the article that other researchers replicated Pons and Fleishman's results in 1990. Nothing ever came of it, and the work ended, because it was drowned out by an avalanche of skepticism in the 'scientific' community.
That is just so typical of history on this planet.
