I have many things that are a PIA to change oil in because they need to be tipped over to drain the oil. Lawnmowers and generators and other things around the house. I had just finished a back breaking day changing the oil in all these things and had only the car to do, when this arrived. I decided to give it a try. I never had an oil change go so smoothly. I sucked the oil out in about 10 minutes and poured it into an empty container for recycle and poured the fresh oil in the car. Finished in about 15 minutes and did not lay on the ground or even get my hands oily. This will be an absolute necessary device for the transaxle in my lawn tractor that is without a drain plug. But very conventient for the jobs that don't need it but still come in very handy. No more picking up the lawn mower or edger or generator to pour out dirty oil and slopping oil all over the floor for me. The suction tube reminds me of a bicycle brake cable. It is small and stiff and has metal inside. It slides into the dip stick easily and you can feel it hit the bottom of the oil pan. It is not a flimsy rubber tube and am very happy with my purchase. Wish I had it sooner.
