This funnel is perfect for adding oil to my air compressor. The fill hole for my compressor is very small and you can easily waste oil by trying to fill without a funnel. I like how it's extra long because the fill hole is next to other components, wires and switches and with a shorter length funnel the top would be too low, you would still have to aim the pour of the oil to reach the top of the funnel. This long funnel makes it super easy. Other than that there's not much else you can say about a simple funnel. If taken care of this will last a long time.
