It works OK if you're just trying to suck the air out, but doesn't pull a
hard enough vacuum to boil out any accumulated moisture (especially from the
dryer).  So if you have a moisture detector in the system, it will turn
yellow again almost immediately.  But, I've never seen a car with a moisture
detector, so you'll probably never know the difference.
