I have had my vista cruies control on my bike for well over a year. I started using them back in the early 80's and never had any trouble with using them. My only suggestion is to make sure that while it is engaged that you can still twist the throttle to decrease your speed. You do not want it so tight that it will be hard. It is a nice additon for me and I have no second thoughts about using it safetly.
