I need to fit a gear door sequencer to my current building project.

I intend to use air retracts (Robart) & servo driven doors & have noticed the Jomar sequencer on the Tower website.

Has anyone had any experience with one of these good or bad? [&o]

I previously use an Ace Servo Master unit on another model but it didn't last long at all. - John.
