I bought this to refill my lawnmower with petrol from the plastic billy cans as the tubes that came with them didn't fit properly and kept falling off. I was forever spilling petrol on the mower and lawn and spending ages cleaning it all off again. After scorching my lawn with petrol yet again I had a eureka moment and scoured amazon for a funnel. Why on earth didn't I do this years ago! I inherited the lawnmower and the filling system and just didn't stop to consider an alternative. This funnel may be simple but it is really well made, a good large size and will surely last me forever. It has made mowing so much more pleasurable as I am not longer stressed when it comes to the refilling part.
