Active suspension

Anybody heard of Roadmaster Active Suspension. Anybody useing it and how do you like it

Had one on my Dodge for a short period.....I did not like it. They fail to mention it raises the back end up to 4" and stays up. It made the truck ride somewhat harsher/ bouncy even though they claim it won't. Its very hard to adjust once its installed too. I think air bags are much better for the same cost.
