Query: Yet another manufacturer who has ruined an amazing product

I never understand why some manufacturers will create an amazing product and then decide they need to "fix" what isn't broken. And it never fails that when they do they ruin it. (Maybe the issue is that what's "broken" is their profit margins.) I had been using this product for maybe 15 years with great success. When I ran out of my last jug, I came here to Amazon to buy another and saw there were some negative reviews about the smell. Since I always found the smell very pleasant, I wasn't sure why people were leaving these reviews; I thought maybe they just didn't like it. Then, I saw there was an "old formula" being sold. Figuring they made a change, I decided to play it safe and get the "old" one. I didn't receive the old formula. (The seller was "Washington Blvd Sales".) Instead, I received what I'm positive must be the new formula -- which is awful. It has a headache-inducing perfume, reminiscent of what I remember lice shampoo smelling like. Not only does it not deter my cats peeing in the same spot, it doesn't seem to get rid of the urine smell anymore. I made the mistake of not trying it on a surface before using it. In my defense, I bought the "old formula" and assumed it was the same product I've been purchasing for years. Well, I sprayed my couch with it and now it smells like pee and this dreadful perfume. Thanks, Spectrum Brands. Your "new formula" has wasted my money and possibly ruined my couch. :(
