First experience with an extractor and I love it.  I'm not able to compare it to others but I am sold on extractors in general.  It's amazing that everyone doesn't use one.  I used it to change the oil on my Mini Cooper and it was great not jacking up the car.  I literally didn't spill a drop or get a drop in my hands.  I've heard from other research it removes at least as much as the old fashion method.  The only down side is that even with hot oil it took a good 20 minutes to extract.
