This is not Dorman, although judging by the article. Don't work in a car.
They work if you don't mind using them manually. But even if it's hooked up to a vacuum pump, nobody's going to apply it, hooked up to a smoke generator to find a leak, and leak out of the bellows inside the actuator. One of the two works. Compared to a local Dorman part, Dorman says "WARN" on it. Maybe it's some kind of failure?
Cons
- speed
