Some chemical products are good, some aren't. I wasn't sure I would spend that much on a leather set but I was glad I did Great set, bought a New Beetle for resale and the seats and steering wheel were so dirty and dry, mostly the steering wheel , I used the cleanser, then the conditioner, then the serum and WOW! looks like a new steering wheel. The seats turned out fantastic, I would recommend this kit to anyone and would buy again. I haven't used a leather scent spray, I don't really like the smell of leather.
