I've been using Ultra with no issues.
Used some today with a TON of dog ****, poop, and hairball, wished I had taken pics like Jeff. I mixed mine @ 6oz/gallon and added 2oz/gallon of odorcide. Everything looked and smelled great. Protected with Fiber Cop baby powder scent.
The last 4 clients have all said great things about the scent in Ultra. I thought there was a need to get the no odor one but there isn't, the smell of it goes away in 30-45 minutes, by the time you do the 2nd story and go do the 1st the fresh scent goes away.
