This does the job, and once started will require minimal to no pumping to complete. Spare o-rings are included. However it needs a few tweaks to really be a great 5 star product. -mine had seams on the main container top cap that were not molded properly. I had to cut them with a knife to be able to fit the vacuum cap in -the instructions are useless. There are other accessories included that are not explained. -the hoses included are really stiff, especially in colder weather. This makes clean-up a problem since its hard to separate and store them without drips. The hoses are springy and want to spray oil so be careful when you separate the various extensions or when you first remove them out of the dipstick hole -the vacuum cylinder has a small bleed valve that is not explained at all. However when I used the product, it stopped draining and pumping no longer worked. Needed to purge this valve to get it going again - which I discovered entirely by accident -this valve is also how you stop the vacuuming action when the container is getting full, instead of just yanking the hose out -lift handle included on the bottom of the product, but its a single wire which digs into your hand when lifting a container filled with oil.
