Good product but NOT for pet training
I had previously used Simple Solutions on "mistakes" made by my new dog. It works great! THIS IS NOT THE SAME thing and I would not use it on carpet or flooring. It has hydrogen peroxide in it. It works wonderfully to clean the shower and to use in the laundry and there may be many more uses I have not tried. I got the "buy 4/get one free" deal which made each one only $4.50 (free shipping) and at the pet store it is $12.99 AND you have to pay tax. I am going to get the original Simple Solutions to keep on hand in case "Pico" makes another "mistake".

didn't work on cat pee
I have a cat who has decided to mark the world (i.e., my house) as his. All the furniture has been soaked, and I've already put zippers in the couch cushions and replaced the stuffing with pillows to make then easy to wash. I picked this up on impulse at Petsmart, along with a gallon of refill. I was excited because the package said you can use it in the laundry. Unfortunately, it not only doesn't remove cat pee smell, but leaves a nasty smell of it's own when it dries. I haven't noticed much difference in laundry, but this weekend he's been on a tear: walls, cushions, blankets. I've squirted almost the entire bottle on stuff to no avail. That's why I'm here on Amazon looking for something else. Once this dries, the smell comes back. Maybe it works better on barf or something, but not cat pee!

kill the cat
Cat pee is difficult. My cat has ruined a lot of my stuff. When she peed in my new trumpet case I had felinocidal thoughts. This product took the edge off that smell but three weeks later you can still tell. The good thing is that it doesn't add a gross chemical smell to try to cover and there was no damage to the color of the fabric. Anyone want a cat?

Not so good
I generally buy Natures Miracle at PETsMART and it works great. This item however leaves an odor and does not do a great job at removing pet urine. It will work a bit, but I would recommend other products.

absolutely horrible!!!!!!!!!
I too was excited after reading all the positive reviews about this product. I was so disappointed after I used it and it did NOTHING AT ALL!
