I've used their cleaner and conditioner, we have tons of it at my house, my mom and sister are both horse lovers and both ride.
I used to use them both as a combo, but just tried woolite in place of the cleaner and I feel like it works a little bit better. I still use their conditioner though.
I've had the sticky seat problem too, but like the person above me said, it was because I didn't do the final buffing off step. That is what makes the difference, and is very easy to do. I have to echo his thoughts on the heat too, it seems to work better in the summer for me than in the winter in the garage (notably coldeR)
