Product review (1 stars): HVAC Super Pro Failed
My husband used this product when he moved our HVAC system into the attic.  My husband has studied and even taught HVAC repair, so, he researched the product before he used it.  Unfortunately, every single copper joint this product was used on failed.  It cost me almost $1,500 for the repairs.  So, buyer beware...this product does not work as it says on its labeling.
