Urine Gone Fast-Acting Enzyme-Based Stain & Odour Eliminator Solution

Has anyone compared this brand to the rocco and roxie urine eliminator? The later is twice the price and i wondered if one works better than the other

Is this product safe for wool carpet?

Has anyone used this on an oak hardwood floor and did it remove any stains?

I see some great reviews for this product ridding of odor but does it stop re-marking? thats my problem but then maybe he'll find a new spot help!
