My first shipment arrived empty the USPS showed it to me but did not deliver it was returned by the USPS After a couple of weeks I called Zero Oder and requested a replacement which they sent even though the USPS had not returned the damaged product, I got a call from Zero Oder the the USPS had returned the product and they would reship the same day I received the product from my call.
I have been using Zero Oder to help clean my cat trees and litter boxes ever since it was reviewed in Cat Nip several years ago.
This is the BEST product I have found to eliminate any odor from my home.
I highly recommend this product.
I've been using and recommending Zero Odor for years. I very much like that the Pro comes in gallon bottles, as it reduces packaging, and with 7 cats and a dog, I use quite a bit. I like the sprayer and the larger spray bottles, too. Both regular and Pro are very effective - I can't say one is more so than the other for my own applications, but overall I prefer the Pro.
I keep this around all the time. with 3 cats and a puppy, it is a life saver.
