    Very fast shipping. Not a bad deal with free shipping. Bought this product to replace an aerosol product that is no longer available. I cannot comment yet about the quality of this product.

    I'm very please with the service that I recieved. The only thing and I'm at fault just as much, I was told be my heating and cooling man that we had to change the filters and that is a 3to 4 hundred cost. So needless to say we didn't change them we just kept cleaning them. Years later when we thought we would start changing them one by one, and found you on the internet we talked to a very helpfull person who informed us that all we needed was this spay (which maybe had we read our instuctions we would have known this) long story short we saved a lot of money. Thank you.

    Product was easy to use. Spray does smell initially (which they did note on the bottle) and it does go away rather quickly. It's best to apply either outdoors or in well ventilated area.

    Product shipped quickly, but no packing slip with product. Website not as easy to navigate as others, but customer service rep was helpful.

    We have 40 large filters on the Inverters that we operate in the dusty farming town of Mendota. We had our initial cleaning of the filters in November 2010, and sprayed the filters afterward with Filter Coat adhesive, as instructed. We'll see the end result of this in May of 2011. The application went smoothly enough, which is why I have given it an OK rating so far.
