Bests & Worsts Reviews from Amazon

Well, not much to say. They arrived quickly. I followed the directions. We did have sign of mold in each of the three we ordered. However, in the place we expected there to be plenty of mold only had one growth, whereas the other two had more than we thought. So we have order a giraffe endoscope camera that we can hook to our computer and drill small holes in the areas we suspect and use the camera rather than having to remove the walls, ceiling and flooring. I did look up to see what different kinds of mold look like growing in a petri dish and while we do have some mold, we don't have the dangerous black mold, so I did not send in the trays as I have in the past. If this is your first time using these, I guarantee you will have mold growth. Take good photos of the trays before mailing in so you have them to look back on if you have to do it again or do it in a different place. That way you can save money for not having to mail everything in. Also, if you do more than one and you see similar type growths, don't send them all in, just send the one with the most growth or the one that has all the different kinds of growth. Hope this helps
