The biggest issue I've had with this accessory are the clutches. I've tweeked it as much as I can, replaced the solenoids, springs etc but it can still be a bit touchy. Two things have observed.
1. Sometimes the clutches stick. So if you want to go left and nothing happens I hit right for a sec and then left and it works. Same for up / down.
2. It seems to like higher voltages somewhere around 18v. If you have it connected to a variable voltage feed then you can find your "sweet spot".
