I originally got this because taking off the lower engine cover to get at the drain plug is more of a pain in the ass than the actual oil change. The reason I love this sooooooo much is that I can now do a full oil change in my TDI without lifting the car AND I don't spill a drop of oil this way. Another great use is changing automatic transmission fluid and power steering fluid. Another bonus is I'm not as concerned about overfilling fluids because I can remove a little bit so easily.
