I don't really need this for eternity would be nice but bought it for a project. Works well, I can leave the can (close the spout) and it still works a few days later. I've used it 3 or 4 times so far, no leaks, and it works fine. I like the adjustable nozzle. Sometimes you need a good flow and sometimes I need to fill a big gap. Works for both. It seems easy to take apart when I need to clean it.
