These are fantastic for easy oil changes, however, they are not that well made for durability. My first one stopped withdrawing oil after about 4 months of use, I opened it up to discover the pump rotor had broken. Shortly after purchasing the second one, I noticed it started smoking at start up but then goes away. I kept the original one because the motor is still good and might be needed. Overall, they are inexpensive and fantastic when they work. I will buy yet another one if needed.
