I ordered this product to save money instead of having my Basement/Crawlspace contractor purchase and recharge me as a middleman. The product came to me very quickly and in good shape. The contractor who specializes in mold and radon commented that this was much higher quality product than what his company uses. (it would have been $1000 more also). He loved working with it, and said I will never have issues with mold, dust, or vapor. Also, customer service on the phone was excellent. I would purchase from this company again.
