I have a set of weekend warrior on my Polaris that have been good and have been in place since 2006 and I have a set of Kolpin ones on my Kawasaki, they have been installed since 2003 and still work. Looking on line, it looks like the design of what I have has changed. The only thing I can say about the weekend warrior ones is that if I try to change from high to low too fast it won't change. I've learned to give it about a minute before trying to change the setting. Both sets only have a high and low.
