There’s not much more to say about this. Don’t buy these: https://amzn.to/3Zh0Dbc or these: https://amzn.to/3ZczUwJ They are a total waste of money. They give false positives on many many substrates (including most metal), to the point that they have zero reliability. The only test kits that work well and consistently are LeadCheck swabs and they are only good in certain applications. Please read this for context if you want to know when it might be appropriate to use LeadCheck swabs.

Thank you for the warning on these. I had used these around my house. It turned color on our door knobs. I was quite upset and replaced most of them. Then saw this post, bought the 3M tests and retested. The 3M ones did not change color at all. Sounds like this common problem false positives? Will make sure to use only 3M going forward.
