anyone try the Revenator?

I tried one of their boxes and it was a big disappointment. I wanted the Rev Limiter feature the box offered. Unfortunately it made my timing jump all over the place and I could never get it sorted out. Called and tried to work through the issues with them but never could. They acknowledged they were having some trouble with a batch of their boxes at one time and told me a new version would be coming out to resolve the varying timing problem that myself and others were encountering. They also offered to send me one of their new prototype boxes for testing but it never showed up. Finally after a year of waiting I went another direction. If it were me I would return the box and never look back.
