Bests & Worsts Reviews from Amazon

This has a lot of good reviews on it and of course most people sent it to the lab there's not many that said you could use it by yourself without sending to a lab. So I wanted to say my 2 cents on how this works. I swab two areas and could have easily put more on there I swab the areas and stuck it on the potato stuff that they gave us and let it sit in warm weather with a bag over it within 3 days I started noticing the ones that were positive for mold growing and the other ones did nothing. It works extremely well and did not require sending off although if you want some lab results you will pay more.
