They didn't change the accuracy of the silver metal tester, in all cases it was hard to read accuracy.

These are great stones for testing metal content. And having a different size for each makes it easy to remember which one is which. If you’ve got a big mixed batch to get through it goes a lot faster.They’re solid, sturdy stones with enough grit to get a sample but not destroy your piece. Good size for easy storage too.

These little stones work well and are strong and durable. I am a practicing jewelry appraiser and these have been it to use! You can use them to test again and again and again. This is a really great value and comes with 3 stones however, it does not come with the neutralizer. The photos also show a bottle of acid and it does not include acid. This is something they should make sure is clear to the consumer so that there isn’t any confusion. Other than that, these are pretty decent little testing stones.
