Doing a little research the oil extractors seem to be a must on inboard boat engines. My purchase was pointed toward oil changes on my lawn equipment. I used it on my pressure washer, big Billy Goat blower, Honda lawn mower used for trimming and a 48" zero turn lawn mower a SCAG Freedom. Other than the SCAG the other powered items were difficult to change the oil in and always resulted in a messy cleanup. Almost immediately I changed oil in all of the lawn equipment. The Hydro-Turf is well designed and I followed the instructions in regarding to pumping. The tubing that goes into the dip stick is easy to insert and sucks out the oil easily with no mess. Another feature I like was the transparent tank is marked with quart hashmarks so you know that the right amount oil has been extracted. After use I elevated the hose and it completely cleared its self of oil. The unit comes with a handy pouring spout that is easy to empty the container. The pump detaches for easy storage. My usage has been  limited so I have no idea of long term durability but it seems to be a  high quality well thought out product.
