I ordered this back in June of 2015 and have used it several time.  I really am very pleased.  The product performs exactly as advertised.  I use it on small engines like lawn mowers, pressure washers, tillers, etc.  I warm up a cold engine for 2 minutes, shut off,  and then extract the oil via the oil fill port.  I do tip some units slightly towards the oil fill port and start the vacuum extraction process.  While it does not take long at all,  I can pump up the unit and walk away leaving it to extract.  Highly recommend!
