What you're describing is my experience with them as well. My parent's town in Ohio added one [1] and there was an uproar, but it's worked surprisingly well.
It replaced a very dangerous 4 way stop/traffic light intersection that very regularly saw accidents due to the geography (hilly) and the road layout (straight into the intersection after a mile of rural road).
