Used it to put oil into my motorcycle, at job at which this funnel excelled thanks to its extra long "nozzle", as it didn't require me to hold the funnel in place while doing so. Also used it to pour kerosene into a spray once, and the funnel didn't seem affected. Very easy to clean, just ran down water through it, although I wouldn't use it for the kitchen now. It can also be used to improve your audition, by amplifying noises around you or used as a horn.
